The results show the severe plastic deformation processing improves the strength of all magnesium alloys, but deformation localization can take place in the Mg-Zn-Ca and Mg-Y-RE alloys. The occurrence of deformation localization is associated with low strain rate sensitivity in these alloys and with severe corrosion localization.

Friction stir welding is a solid state welding process which is most suitable for the welding of nonferrous alloys, especially aluminum and magnesium alloys. Aluminum and magnesium alloys are widely used for structural applications of all types of automobiles due to their superior mechanical properties with their low density. This paper deals with the critical review of the different properties (like tensile strength, microhardness, impact strength, corrosion resistance, and metallurgical investigation on SEM) obtained by the FSW of aluminum and magnesium alloys. After a critical review of the existing published literature on concerned topics, all the properties of welding joins are compared in the tabulated manner to optimize the selection of materials and FSW parameters according to mechanical and tribological properties. Different tool designs used for the FSW process are also thoroughly studied, and the influence of the design of the tool used in FSW on the different properties has also been incorporated in this paper. It has been observed from the existing published literature that FSW is the most effective and practical technique for joining the non ferrous alloys especially aluminum and magnesium alloys, and among the different FSW tools, left hand threaded tri-flute (LHTTF) tool is best for the welding of non ferrous alloys like aluminum and magnesium alloys which gives the superior mechanical properties to welding joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum" title="aluminum">aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20applications" title=" structural applications"> structural applications</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20design" title=" tool design"> tool design</a> </p> <a href="https://publications.waset.org/abstracts/108193/a-review-on-the-studies-on-mechanical-and-tribological-properties-of-aluminum-and-magnesium-alloys-welded-by-friction-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">801</span> Relationship between Extrusion Ratio and Mechanical Properties of Magnesium Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20H.%20Jeon">C.

One way of resolving these issues is to reduce product weight. Magnesium alloys are considered promising candidates because of their lightness. Various studies have been conducted on using magnesium alloy instead of conventional iron or aluminum in mechanical parts, due to the light weight and superior specific strength of magnesium alloy. However, even stronger magnesium alloys are needed for mechanical parts. One common way to enhance the strength of magnesium alloy is by extruding the ingot. In order to enhance the mechanical properties, magnesium alloy ingot were extruded at various extrusion ratios. Relationship between extrusion ratio and mechanical properties was examined on extruded material of magnesium alloy.

In this work we have presented a comparative study on the behavior of the precipitation reactions during different heat treatment in two different Al-Mg alloys (Al–8 wt. % Mg and Al–12 wt. % Mg). For this purpose, we have used various experimental techniques as dilatometry, calorimetry, optical microscopy, and microhardness measurements.

However, the high biodegradation rate of existing Mg alloys in the physiological environment of human body leads to losing mechanical integrity before adequate bone healing and producing a large volume of hydrogen gas. Therefore, slowing down the biodegradation rate of Mg alloys is a critical task in developing new biodegradable Mg alloy implant materials. One of the most effective approaches to achieve this is to strategically design new Mg alloys with low biodegradation rate, excellent biocompatibility, and enhanced mechanical properties. Our research selected biocompatible and biofunctional alloying elements such as zirconium (Zr), strontium (Sr), and rare earth elements (REEs) to alloy Mg and has developed a new series of Mg-Zr-Sr-REEs alloys for biodegradable implant applications. Research results indicated that Sr and Zr additions could refine the grain size, decrease the biodegradation rate, and enhance the biological behaviors of the Mg alloys. The REE addition, such as holmium (Ho) and dysprosium (Dy) to Mg-Zr-Sr alloys resulted in enhanced mechanical strength and decreased biodegradation rate. In addition, Ho and Dy additions (≤ 5 wt.%) to Mg-Zr-Sr alloys led to enhancement of cell adhesion and proliferation of osteoblast cells on the Mg-Zr-Sr-Ho/Dy alloys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20and%20biodegrade%20properties" title=" mechanical and biodegrade properties"> mechanical and biodegrade properties</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20earth%20elements" title=" rare earth elements"> rare earth elements</a> </p> <a href="https://publications.waset.org/abstracts/113098/biodegradable-magnesium-alloys-with-addition-of-rare-earth-elements-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113098.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">798</span> Analysis of Magnesium Alloy Wheel Forming Technologies for Light Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Dziubinska">Anna Dziubinska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The applications of magnesium alloys in transport include all kinds of vehicle wheels for cars, motorcycles, bicycles, trolleys, etc. Modern technologies of manufacturing products from these materials have been noticeably improved recently, creating new possibilities for their application.

The magnesium alloys containing Mg, Zn, Ca as an alloying element are the subject of the particular interest. These elements are the nutrients for the human body, which provide their high biocompatibility. In this work, we investigated the effect of severe plastic deformation (SPD) on the mechanical and corrosion properties of Mg-Zn-Ca and Mg-Zn-Ca-Mn alloys containing from 2 to 4 wt.% Zn; 0.7 wt.% Ca and up to 1 wt.% Mn. Hot extrusion was used as a method of intensive plastic deformation. The temperature of hot extrusion was set to 220 °C and 300 °C. Metallographic analysis after hot extrusion shows that the grain size in the studied alloys depends on the deformation temperature. The grain size for all of investigated alloys is in the range from 3 to 7 microns, and 3 μm corresponds to the extrusion temperature of 220 °C. Analysis of mechanical properties after extrusion shows that extrusion at a temperature of 220 °C and alloying with Mn increase the strength characteristics and decrease the ductility of studied alloys. A slight anisotropy of properties in the longitudinal and transverse directions was also observed. Measurements of corrosion properties revealed that the addition of Mn to Mg-Zn-Ca alloys reduces the corrosion rate. On the other hand, increasing the Zn content in alloys increases the corrosion rate. The extrusion temperature practically does not affect the corrosion rate.

Friction Stir Welding (FSW), a solid state joining process, successfully welds difficult to weld similar and dissimilar aluminum and magnesium alloys. Two tool rotation speeds were selected by keeping the transverse speed constant to weld similar and dissimilar alloys. Similar(Al to Al) and Dissimilar(Al to Mg) weld joints were obtained by FSW. SEM scans revealed that higher tool rotation fragments the coarse grains of base material into fine grains in the weld zone. Also, there are less welding defects in weld joints obtained with higher tool rotation speed. The material of dissimilar alloys was mixed with each other forming recrystallised new intermetallics. There was decrease in hardness of similar weld joint however there is significant increase in hardness of weld zone in case of dissimilar weld joints due to stirring action of tool and formation of inter metallics. Tensile tests revealed that there was decrease in percentage elongation in both similar and dissimilar weld joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloys" title="aluminum alloys">aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title=" magnesium alloys"> magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/17732/study-of-microstructure-and-mechanical-properties-obtained-by-fsw-of-similar-and-dissimilar-non-ferrous-alloys-used-in-aerospace-and-automobile-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17732.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">793</span> Microstructure Study of Melt Spun Mg₆₅Cu₂₅Y₁₀</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Regev">Michael Regev</a>, <a href="https://publications.waset.org/abstracts/search?q=Shai%20Essel"> Shai Essel</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Katz-Demyanetz"> Alexander Katz-Demyanetz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium alloys are characterized by good physical properties: They exhibit high strength, are lightweight and have good damping absorption and good thermal and electrical conductivity. Amorphous magnesium alloys, moreover, exhibit higher strength, hardness and a large elastic domain in addition to having excellent corrosion resistance. These above-mentioned advantages make magnesium based metallic glasses attractive for industrial use. Among the various existing magnesium alloys, Mg₆₅Cu₂₅Y₁₀ alloy is known to be one of the best glass formers. In the current study, Mg₆₅Cu₂₅Y₁₀ ribbons were produced by melt spinning, their microstructure was investigated in its as-cast condition, after pressing under 0.5 GPa for 5 minutes under different temperatures - RT, 500C, 1000C, 1500C and 2000C - and after five minute exposure to the above temperatures without pressing. The microstructure was characterized by means of X-ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), High Resolution Scanning Electron Microscope (HRSEM) and High Resolution Transmission Electron Microscopy (HRTEM). XRD and DSC studies showed that the as-cast material had an amorphous character and that the material crystallized during exposure to temperature with or without applying stress. HRTEM revealed that the as-cast Mg65Cu25Y10, although known to be one of the best glass formers, is nano-crystalline rather than amorphous. The current study casts light on the question what an amorphous alloy is and whether there is any clear borderline between amorphous and nano-crystalline alloys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metallic%20glass" title="metallic glass">metallic glass</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=melt%20spinning" title=" melt spinning"> melt spinning</a>, <a href="https://publications.waset.org/abstracts/search?q=amorphous%20alloys" title=" amorphous alloys"> amorphous alloys</a> </p> <a href="https://publications.waset.org/abstracts/55640/microstructure-study-of-melt-spun-mg65cu25y10" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">792</span> Magnesium Alloys Containing Y, Gd and Ca with Enhanced Ignition Temperature and Mechanical Properties for Aviation Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji%C5%99%C3%AD%20Kub%C3%A1sek">Jiří Kubásek</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Min%C3%A1rik"> Peter Minárik</a>, <a href="https://publications.waset.org/abstracts/search?q=Kl%C3%A1ra%20Hosov%C3%A1"> Klára Hosová</a>, <a href="https://publications.waset.org/abstracts/search?q=Stanislav%20%C5%A0a%C5%A1ek"> Stanislav Šašek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jozef%20Vesel%C3%BD"> Jozef Veselý</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitka%20Str%C3%A1sk%C3%A1"> Jitka Stráská</a>, <a href="https://publications.waset.org/abstracts/search?q=Drahom%C3%ADr%20Dvorsk%C3%BD"> Drahomír Dvorský</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalibor%20Vojt%C4%9Bch"> Dalibor Vojtěch</a>, <a href="https://publications.waset.org/abstracts/search?q=Milo%C5%A1%20Jane%C4%8Dek"> Miloš Janeček</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mg-2Y-2Gd-1Ca and Mg-4Y-4Gd-2Ca alloys were processed by extrusion or equal channel angular pressing (ECAP) to analyse the effect of the microstructure on ignition temperature, mechanical properties and corrosion resistance. The alloys are characterized by good mechanical properties and exceptionally high ignition temperature, which is a critical safety measure. The effect of extrusion and ECAP on the microstructure, mechanical properties and ignition temperature was studied. The obtained results indicated a substantial effect of the processing conditions on the average grain size, the recrystallized fraction and texture formation. Both alloys featured a high strength, depending on the composition and processing condition, and a high ignition temperature of ≈1100 °C (Mg-4Y-4Gd-2Ca) and ≈950 °C (Mg-2Y-2Gd-1Ca), which was attributed to the synergic effect of Y, Gd and Ca oxides, with the dominant effect of Y₂O₃. The achieved combination of enhanced mechanical properties and the ignition temperature makes these alloys a prominent candidate for aircraft applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title="magnesium alloys">magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20ignition%20temperature" title=" enhanced ignition temperature"> enhanced ignition temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=ECAP" title=" ECAP"> ECAP</a> </p> <a href="https://publications.waset.org/abstracts/157860/magnesium-alloys-containing-y-gd-and-ca-with-enhanced-ignition-temperature-and-mechanical-properties-for-aviation-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157860.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">791</span> Development of A MG-Gd-Er-Zn-Zr Alloy with Ultrahigh Strength and Ductility via Extrusion, Pre-Deformation, and Two-Stage Aging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linyue%20Jia">Linyue Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenbo%20Du"> Wenbo Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhaohui%20Wang"> Zhaohui Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ke%20Liu"> Ke Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubo%20Li"> Shubo Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the great potential for weight reduction in aerospace and automotive industries, magnesium-rare earth (Mg-RE) based alloys with outstanding mechanical performance have been widely investigated for decades. However, magnesium alloys are still restricted in engineering applications because of their lower strength and ductility. Hence, there are large spaces and challenges in achieving high-performance Mg alloys. This work reports an Mg-Gd-Er-Zn-Zr alloy with ultrahigh strength and good ductility developed via hot extrusion, pre-deformation, and two-stage aging. The extruded alloy comprises fine dynamically recrystallized (DRXed) grains and coarse worked grains with a large aspect ratio. Pre-deformation has little effect on the microstructure and macro-texture and serves primarily to introduce a large number of dislocations, resulting in strain hardening and higher precipitation strengthening during subsequent aging due to more nucleation sites. As a result, the alloy exhibits a yield strength (YS) of 506 MPa, an ultimate tensile strength (UTS) of 549 MPa, and elongation (EL) of 8.2% at room temperature, showing superior strength-ductility balance than the other wrought Mg-RE alloys previously reported. The current study proposes a combination of pre-deformation and two-stage aging to further improve the mechanical properties of wrought Mg alloys for engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title="magnesium alloys">magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-deformation" title=" pre-deformation"> pre-deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=two-stage%20aging" title=" two-stage aging"> two-stage aging</a> </p> <a href="https://publications.waset.org/abstracts/123503/development-of-a-mg-gd-er-zn-zr-alloy-with-ultrahigh-strength-and-ductility-via-extrusion-pre-deformation-and-two-stage-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">790</span> Influence of Maximum Fatigue Load on Probabilistic Aspect of Fatigue Crack Propagation Life at Specified Grown Crack in Magnesium Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seon%20Soon%20Choi">Seon Soon Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The principal purpose of this paper is to find the influence of maximum fatigue load on the probabilistic aspect of fatigue crack propagation life at a specified grown crack in magnesium alloys.

It is necessary to consider probabilistic characteristics of a structural material because a fatigue behavior of a structure has a randomness and uncertainty. The purpose of this study is to find the characteristics of the cumulative distribution function (CDF) of the grown crack size at a specified fatigue crack propagation life and to investigate a statistical crack propagation in magnesium alloys. The statistical fatigue data of the grown crack size are obtained through the fatigue crack propagation (FCP) tests under different maximum fatigue load conditions conducted on the replicated specimens of magnesium alloys. The 3-parameter Weibull distribution is used to find the CDF of grown crack size. The CDF of grown crack size in case of larger maximum fatigue load has longer tail in below 10 percent and above 90 percent. The fatigue failure occurs easily as the tail of CDF of grown crack size becomes long. The fatigue behavior under the larger maximum fatigue load condition shows more rapid propagation and failure mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cumulative%20distribution%20function" title="cumulative distribution function">cumulative distribution function</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20crack%20propagation" title=" fatigue crack propagation"> fatigue crack propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=grown%20crack%20size" title=" grown crack size"> grown crack size</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title=" magnesium alloys"> magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20fatigue%20load" title=" maximum fatigue load"> maximum fatigue load</a> </p> <a href="https://publications.waset.org/abstracts/76512/characteristics-of-cumulative-distribution-function-of-grown-crack-size-at-specified-fatigue-crack-propagation-life-under-different-maximum-fatigue-loads-in-az31" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76512.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">788</span> Influence of Coenzyme as a Corrosion Barrier for Biodegradable Magnesium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minjung%20Park">Minjung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimin%20Park"> Jimin Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Youngwoon%20Kim"> Youngwoon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyungseop%20Han"> Hyungseop Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Myoungryul%20Ok"> Myoungryul Ok</a>, <a href="https://publications.waset.org/abstracts/search?q=Hojeong%20Jeon"> Hojeong Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyunkwang%20Seok"> Hyunkwang Seok</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuchan%20Kim"> Yuchan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium is an essential element in human body and has unique characteristics such as bioabsorbable and biodegradable properties. Therefore, there has been much attention on studies on the implants based on magnesium to avoid subsequent surgery. However, high amount of hydrogen gas is generated by relatively severe corrosion of magnesium especially in aqueous condition with chloride ions. And it contributes to the causes of swelling of skin and causes consequent inflammation of soft tissue where is directly in contact with implants. Therefore, there is still concern about the safety of the using biodegradable magnesium alloys, which is limited to various applications. In this study, we analyzed the influence of coenzyme on corrosion behavior of magnesium. The analysis of corrosion rate was held by using Hanks’ balanced salt solution (HBSS) as a body stimulated fluid and in condition of 37°C. Thus, with deferring the concentration of the coenzyme used in this study, corrosion rates from 0.0654ml/ cm² to 0.0438ml/cm² were observed in immersion tests. Also, comparable results were obtained in electrochemical tests.

In this review, attempt has been done to collect the literature related to wear behavior of magnesium matrix composites fabricated through various processing techniques such as stir casting, powder metallurgy, friction stir processing etc. Effect of different reinforcements, reinforcement content, reinforcement size, wear load, sliding speed and time have been studied by different researchers in detail. Wear mechanism under different experimental condition has been reviewed in detail. The wear resistance of magnesium and its alloys can be enhanced with the addition of different reinforcements. Wear resistance can further be enhanced by increasing the percentage of added reinforcements. Increase in applied load during wear test leads to increase in wear rate of magnesium composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hardness" title="hardness">hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20matrix%20composites" title=" magnesium matrix composites"> magnesium matrix composites</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement"> reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/52187/review-on-wear-behavior-of-magnesium-matrix-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">785</span> Scanning Electrochemical Microscopy Studies of Magnesium-Iron Galvanic Couple</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akram%20Alfantazi">Akram Alfantazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tirdad%20Nickchi"> Tirdad Nickchi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium galvanic corrosion plays an important role in the commercialization of Mg alloys in the automobile industry.

Regions in the vicinity of the galvanic couple boundary are very active in the magnesium phase and fully protected in the iron phase. Scanning electrochemical microscopy results showed that the conversion coating provided good corrosion resistance for magnesium in the short-term but fails at long-term testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanic%20corrosion" title=" galvanic corrosion"> galvanic corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electrochemical%20microscopy" title=" scanning electrochemical microscopy"> scanning electrochemical microscopy</a> </p> <a href="https://publications.waset.org/abstracts/92833/scanning-electrochemical-microscopy-studies-of-magnesium-iron-galvanic-couple" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92833.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">784</span> Fundamental Research Dissension between Hot and Cold Chamber High Pressure Die Casting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahil%20Kumar">Sahil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Surinder%20Pal"> Surinder Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Kapoor"> Rahul Kapoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is focused on to define the basic difference between hot and cold chamber high pressure die casting process which is not fully defined in a research before paper which we have studied. The pressure die casting is basically defined into two types (1) Hot chamber Die Casting (2) Cold chamber Die Casting. Cold chamber die casting is used for casting alloys that require high pressure and have a high melting temperature, such as brass, aluminum, magnesium, copper based alloys and other high melting point nonferrous alloys. Hot chamber die casting is suitable for casting zinc, tin, lead, and low melting point alloys. In hot chamber die casting machine, the molten metal is an integral pan of the machine. It mainly consists of hot chamber and gooseneck type metal container made of cast iron. This machine is mainly used for low melting alloys and alloys of metals like zinc, lead etc. Metals and alloys having a high melting point and those which are having an affinity for iron cannot be cast by this machine, which could otherwise attack the shot sleeve and damage the machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20chamber%20die%20casting" title="hot chamber die casting">hot chamber die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20chamber%20die%20casting" title=" cold chamber die casting"> cold chamber die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=metals%20and%20alloys" title=" metals and alloys"> metals and alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=casting%20technology" title=" casting technology"> casting technology</a> </p> <a href="https://publications.waset.org/abstracts/25342/fundamental-research-dissension-between-hot-and-cold-chamber-high-pressure-die-casting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">618</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">783</span> Use of Magnesium as a Renewable Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafayel%20K.%20Kostanyan">Rafayel K.

Fatigue crack propagation experiments are carried out in laboratory air under three conditions of specimen thickness using AZ31 to investigate a stochastic crack growth behavior.

Considering the fact that companies all over the world look for alloys with the highest values of mechanical properties coexisting with a reasonable electrical conductivity made it necessary to develop new materials based on copper, such as copper magnesium alloys with over 2 wt. % of Mg. Though, before such new material may be mass produced it must undergo a series of tests in order to determine the production technology and its parameters. The presented study is based on the numerical simulations calculated with the use of finite element method analysis, where the geometry of the cooling system, the material used to produce the cooling system and the surface quality of the graphite crystallizer at the place of contact with the cooling system and its influence on the temperatures throughout the continuous casting process is being investigated. The calculated simulations made it possible to propose the optimal set of equipment necessary for the continuous casting process to be carried out in laboratory conditions with various casting parameters and to determine basic materials properties of the obtained alloys such as hardness, electrical conductivity and homogeneity of the chemical composition.

Product designing proceeds in numerous stages and in most of them there are open questions with not only one correct solution but better and worse ones. This paper overviews the Diesel engine body construction materials mentioned in the literature and discusses a certain practical method to select materials for a cylinder head and a Diesel engine block as a prototype. The engine body, depending on its purpose, is most frequently iron or aluminum. If it is important to optimize parts to achieve low weight, aluminum alloys are usually applied, especially in the automotive and aviation industries. In the latter case, weight is even more important so new types of magnesium alloys which are even lighter than aluminum ones are developed and used. However, magnesium alloys are, for example, more flammable and not enough strong so, for safety reasons, this type of material is not used solely in engine bodies.

Magnesium has been favored for the bulk of plugs, requiring development of materials to suit specific field requirements. Herein, the mechanical and dissolution results from equal channel angular pressing (ECAP) of two cast dissolvable magnesium alloy are described. ECAP was selected as a route to increase the mechanical properties of two formulations of dissolvable magnesium, as solutionizing failed. In this study, 1” square cross section samples cast Mg alloys formulations containing rare earth were processed at temperatures ranging from 200 to 350 °C, at a rate of 0.005”/s, with a backpressure from 0 to 70 MPa, in a brass, or brass + graphite sheet. Generally, the yield and ultimate tensile strength (UTS) doubled for all. For formulation DM-2, the yield increased from 100 MPa to 250 MPa; UTS from 175 MPa to 325 MPa, but the strain fell from 2 to 1%. Formulation DM-3 yield increased from 75 MPa to 200 MPa, UTS from 150 MPa to 275 MPa, with strain increasing from 1 to 3%. Meanwhile, ECAP has also been found to reduce the dissolution rate significantly. A microstructural analysis showed grain refinement of the alloy and the movement of secondary phases away from the grain boundary. It is believed that reconfiguration of the grain boundary phases increased the mechanical properties and decreased the dissolution rate. ECAP processing of dissolvable high rare earth content magnesium is possible despite the brittleness of the material. ECAP is a possible processing route to increase mechanical properties for dissolvable aluminum alloys that do not extrude. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equal%20channel%20angular%20processing" title="equal channel angular processing">equal channel angular processing</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolvable%20magnesium" title=" dissolvable magnesium"> dissolvable magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=frac%20plug" title=" frac plug"> frac plug</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/132877/enhancement-of-mechanical-and-dissolution-properties-of-a-cast-magnesium-alloy-via-equal-angular-channel-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132877.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">776</span> Corrosion Response of Friction Stir Processed Mg-Zn-Zr-RE Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vasanth%20C.%20Shunmugasamy">Vasanth C.

However, Mg alloys exhibit a high corrosion rate that restricts their application as a biomaterial. For safe use as biomaterial, it is essential to control their corrosion rates. Mg alloy corrosion is influenced by several factors, such as grain size, precipitates and texture. In Mg alloys, microgalvanic coupling between the α-Mg matrix and secondary precipitates can exist, which results in an increased corrosion rate. The present research addresses this challenge by engineering the microstructure of a biodegradable Mg–Zn–RE–Zr alloy by friction stir processing (FSP), a severe plastic deformation process. The FSP-processed Mg alloys showed improved corrosion resistance and mechanical properties. FSPed Mg alloy showed refined grains, a strong basal texture and broken and uniformly distributed secondary precipitates in the stir zone. Mg, alloy base material, exposed to In vitro corrosion medium showed micro galvanic coupling between precipitate and matrix, resulting in the unstable passive layer. However, FS processed alloy showed uniform corrosion owing to stable surface film formation. The stable surface film is attributed to refined grains, preferred texture and distribution of precipitates. The research results show promising potential for Mg alloy to be developed as a biomaterial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title="biomaterials">biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20plastic%20deformation" title=" severe plastic deformation"> severe plastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title=" magnesium alloys"> magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a> </p> <a href="https://publications.waset.org/abstracts/186884/corrosion-response-of-friction-stir-processed-mg-zn-zr-re-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">43</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">775</span> Phase Segregating and Complex Forming Pb Based (=X-Pb) Liquid Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indra%20Bahadur%20Bhandari">Indra Bahadur Bhandari</a>, <a href="https://publications.waset.org/abstracts/search?q=Narayan%20Panthi"> Narayan Panthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishwar%20Koirala"> Ishwar Koirala</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Adhikari"> Devendra Adhikari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have used a theoretical model based on the assumption of compound formation in binary alloys to study the thermodynamic, microscopic, and surface properties of Bi-Pb and In-Pb liquid alloys. A review of the phase diagrams for these alloys shows that one of the stable complexes for Bi-Pb liquid alloy is BiPb3; also, that InPb is a stable phase in liquid In-Pb alloys. Using the same interaction parameters that are fitted for the free energy of mixing, we have been able to compute the bulk and thermodynamic properties of the alloys. From our observations, we are able to show that the Bi-Pb liquid alloy exhibits compound formation over the whole concentration range and the In-Pb alloys undergo phase separation. With regards to surface properties, Pb segregates more to the surface in In-Pb alloys than in Bi-Pb alloys. The viscosity isotherms have a positive deviation from ideality for both Bi-Pb and In-Pb alloys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetry" title="asymmetry">asymmetry</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi-Pb" title=" Bi-Pb"> Bi-Pb</a>, <a href="https://publications.waset.org/abstracts/search?q=deviation" title=" deviation"> deviation</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Pb" title=" In-Pb"> In-Pb</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20parameters" title=" interaction parameters"> interaction parameters</a> </p> <a href="https://publications.waset.org/abstracts/136406/phase-segregating-and-complex-forming-pb-based-x-pb-liquid-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136406.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">774</span> Effect of Microstructure and Texture of Magnesium Alloy Due to Addition of Pb</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yebeen%20Ji">Yebeen Ji</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimin%20Yun"> Jimin Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwonhoo%20Kim"> Kwonhoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium alloys were limited for industrial applications due to having a limited slip system and high plastic anisotropy. It has been known that specific textures were formed during processing (rolling, etc.), and These textures cause poor formability. To solve these problems, many researchers have studied controlling texture by adding rare-earth elements. However, the high cost limits their use; therefore, alternatives are needed to replace them. Although Pb addition doesn’t directly improve magnesium properties, it has been known to suppress the diffusion of other alloying elements and reduce grain boundary energy. These characteristics are similar to the additions of rare-earth elements, and a similar texture behavior is expected as well. However, there is insufficient research on this. Therefore, this study investigates the behavior of texture and microstructure development after adding Pb to magnesium. This study compared and analyzed AZ61 alloy and Mg-15wt%Pb alloy to determine the effect of adding solute elements. The alloy was hot rolled and annealed to form a single phase and initial texture. Afterward, the specimen was set to contraction and elongate parallel to the rolling surface and the rolling direction and then subjected to high-temperature plane strain compression under the conditions of 723K and 0.05/s. Microstructural analysis and texture measurements were performed by SEM-EBSD. The peak stress in the true strain-stress curve after compression was higher in AZ61, but the shape of the flow curve was similar for both alloys. For both alloys, continuous dynamic recrystallization was confirmed to occur during the compression process. The basal texture developed parallel to the compressed surface, and the pole density was lower in the Mg-15wt%Pb alloy. It is confirmed that this change in behavior is because the orientation distribution of recrystallized grains has a more random orientation compared to the parent grains when Pb is added. <p
