The presented device reduces the effort and cost of single solar cell characterization to a minimum. It enables realistic characterization of cells under sunlight within minutes. In the field of photovoltaic research the common way to characterize a single solar cell or a module is, to measure the current voltage curve. With this characteristic the performance and the degradation rate can be defined which are important for the consumer or developer.

The common objective of many of these methods is to supply classification criteria. The purpose of this study is to present a method for assessing the seismic performance of structures, based on Pushover method, we are particularly interested in reinforced concrete frame structures, which represent a significant percentage of damaged structures after a seismic event. The work is based on the characterization of seismic movement of the various earthquake zones in terms of PGA and PGD that is obtained by means of SIMQK_GR and PRISM software and the correlation between the points of performance and the scalar characterizing the earthquakes will be developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title="seismic performance">seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20method" title=" pushover method"> pushover method</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20of%20seismic%20motion" title=" characterization of seismic motion"> characterization of seismic motion</a>, <a href="https://publications.waset.org/abstracts/search?q=harmfulness%20of%20the%20seismic" title=" harmfulness of the seismic"> harmfulness of the seismic</a> </p> <a href="https://publications.waset.org/abstracts/29929/introduction-of-the-harmfulness-of-the-seismic-signal-in-the-assessment-of-the-performance-of-reinforced-concrete-frame-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29929.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">383</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">14979</span> Cost-Effective, Accuracy Preserving Scalar Characterization for mmWave Transceivers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Salah%20Abdullatif">Mohammad Salah Abdullatif</a>, <a href="https://publications.waset.org/abstracts/search?q=Salam%20Hajjar"> Salam Hajjar</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Khanna"> Paul Khanna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of instrument grade mmWave transceivers comes with many challenges. A general rule of thumb is that the performance of the instrument must be higher than the performance of the unit under test in terms of accuracy and stability. The calibration and characterizing of mmWave transceivers are important pillars for testing commercial products. Using a Vector Network Analyzer (VNA) with a mixer option has proven a high performance as an approach to calibrate mmWave transceivers. However, this approach comes with a high cost. In this work, a reduced-cost method to calibrate mmWave transceivers is proposed. A comparison between the proposed method and the VNA technology is provided. A demonstration of significant challenges is discussed, and an approach to meet the requirements is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mmWave%20transceiver" title="mmWave transceiver">mmWave transceiver</a>, <a href="https://publications.waset.org/abstracts/search?q=scalar%20characterization" title=" scalar characterization"> scalar characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=coupler%20connection" title=" coupler connection"> coupler connection</a>, <a href="https://publications.waset.org/abstracts/search?q=magic%20tee%20connection" title=" magic tee connection"> magic tee connection</a>, <a href="https://publications.waset.org/abstracts/search?q=calibration" title=" calibration"> calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=VNA" title=" VNA"> VNA</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20network%20analyzer" title=" vector network analyzer"> vector network analyzer</a> </p> <a href="https://publications.waset.org/abstracts/149410/cost-effective-accuracy-preserving-scalar-characterization-for-mmwave-transceivers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149410.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">14978</span> Mechanical Properties and Characterization of Ti–6Al–4V Alloy Diffused by Molybdenum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaeddine%20Kaouka">Alaeddine Kaouka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The properties and characterization of Ti-6Al-4V alloys with different contents of Mo were investigated.

This 4-year project has 18 partners and aims at improving the management of contaminated materials arising from decommissioning and dismantling (D&D) operations by proposing an integrated methodology of characterization. This methodology is based on advanced statistical processing and modelling, coupled with adapted and innovative analytical and measurement methods, with respect to sustainability and economic objectives. In order to achieve these objectives, the approaches will be then applied to common case studies in the form of Inter-laboratory comparisons on matrix representative reference samples and benchmarking. Work Package 6 (WP6) ‘Performance analysis and overall uncertainty’ is in charge of the analysis of the benchmarking on real samples, the organisation of inter-laboratory comparison on synthetic certified reference materials and the establishment of overall uncertainty budget. Assessment of the outcome will be used for providing recommendations and guidance resulting in pre-standardization tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decommissioning" title="decommissioning">decommissioning</a>, <a href="https://publications.waset.org/abstracts/search?q=sampling%20strategy" title=" sampling strategy"> sampling strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20and%20development" title=" research and development"> research and development</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20project" title=" European project"> European project</a> </p> <a href="https://publications.waset.org/abstracts/84947/the-european-research-and-development-project-improved-nuclear-site-characterization-for-waste-minimization-in-decommissioning-under-constrained-environment-focus-on-performance-analysis-and-overall-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84947.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">364</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">14976</span> Characterization Microstructural Dual Phase Steel for Application In Civil Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Habibi">S.

Due to the size, possible dangerous composition, and heterogeneity, most of the wastes are located at landfills without a basic geotechnical characterization. This lack of information may have an important influence on the correct stability calculations. This paper presents the results of geotechnical characterization of some industrial wastes disposed at one landfill. The shear strength parameters were calculated based on direct shear test results carried out in a large shear box owned by CEDEX, which has a shear plane of 1 x 1 m. These parameters were also compared with the results obtained in a 30 x 30 cm shear box. The paper includes a sensitive analysis of the global safety factor of the landfill's overall stability as a function of shear strength variation. The stability calculations were assessed for various hydrological scenarios to simulate the design and performance of the leachate drainage system. The characterization was completed with leachate tests to study the potential impact on the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20wastes" title="industrial wastes">industrial wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill" title=" landfill"> landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=leachate%20tests" title=" leachate tests"> leachate tests</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/134798/geotechnical-characterization-of-an-industrial-waste-landfill-stability-and-environmental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134798.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">195</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">14974</span> Synthesis and Characterization of Model Amines for Corrosion Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Vergara">John Vergara</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Palmese"> Giuseppe Palmese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fundamental studies aimed at elucidating the key contributions to corrosion performance are needed to make progress toward effective and environmentally compliant corrosion control.

Creating model building blocks for epoxy/amine coatings is the first step in carrying out these studies. We will demonstrate the synthesis and characterization of model amine building blocks from saturated fatty acids and simple amines such as diethylenetriamine (DETA) and Bis(3-aminopropyl)amine.

Microstructural characterization, as one of the main materials development tools, plays a pivotal role in the production of better clean energy devices. In this study, methods for characterization and studying of the defects and components distribution were performed on the polymer electrolyte membrane fuel cell (PEMFC) and Li-ion battery (LIB) electrodes in 2D and 3D. The particles distribution, porosity, mechanical defects, and component distribution were studied by Scanning Electron Microscope (SEM), SEM-Focused Ion Beam (SEM-FIB), and Scanning Transmission Electron Microscope equipped with Energy Dispersive Spectroscopy (STEM-EDS).

A detailed comparison with a reference powder obtained by SCS, starting from a commercial iron nitrate, was also performed. Several techniques such as X-ray diffraction combined with Rietveld refinement, mass plasma atomic emission spectroscopy, nitrogen adsorption measurements, temperature programmed reduction, X-ray photoelectron spectroscopy, Fourier transform analysis and scanning electron microscopy were used for the characterization of the rust wastes as well as of the perovskite powders. The performance of this ecofriendly material was evaluated by testing the activity and selectivity in the propylene oxidation, in order to use it for the benefit of the environment. Characterization and performance results clearly evidenced limitations and peculiarities of this new approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perovskite%20type%20catalysts" title="perovskite type catalysts">perovskite type catalysts</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20combustion%20synthesis" title=" solution combustion synthesis"> solution combustion synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20diffraction" title=" X-ray diffraction"> X-ray diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=rust%20wastes" title=" rust wastes"> rust wastes</a> </p> <a href="https://publications.waset.org/abstracts/76645/synthesis-of-iron-based-perovskite-type-catalysts-from-rust-wastes-as-a-source-of-iron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76645.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">333</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">14971</span> Preparation and Characterization of Activated Carbon from Animal Bone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getenet%20Aseged%20Zeleke">Getenet Aseged Zeleke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this project was to study the synthesis of activated carbon from low-cost animal beef and the characterization of the product obtained.

They are one of the most challenging issues faced by recyclers, because they are at the present time considered as non-sortable and non-reusable mixtures destined to landfill. However, fines contain a large amount of recoverable materials that could be recycled or reused for the production of solid recovered fuel. This research is conducted in relation to a project named ValoRABES. The aim is to characterize fines and establish a suitable sorting process in order to extract the materials contained in the mixture and define their suitable recovery paths.

In the present work, catalyst for esterification reaction was prepared from waste bone and characterized by various techniques. Bone was deoiled and then sulfonated. Fourier-transform infrared spectroscopy (FTIR) spectra of prepared catalyst predicted –OH vibration at 3416 and 1630 cm⁻¹, S-O stretching at 1124 cm⁻¹ and intense bands of hydroxypatite in a region between 500 and 700 cm⁻¹. X-ray diffraction (XRD) predicts peaks of hydroxyapatite, CaO, and tricalcium phosphate. Scanning electron microscope (SEM) was employed to reveal the presence of non-uniformity deposited fine particles on the catalyst surface that represents active acidic sites. The prepared catalyst was employed to study its performance on esterification reaction between acrylic acid and ethanol in a molar ratio of 1:1 at a set temperature of 60 °C. Results show an equilibrium conversion of 49% which is matched to the commercial catalysts employed in literature.

This paper presents the complete procedure of yarn supercapacitors fabrication process through dip coating technique and its characterization method. The main objective is to study, the effect of varying caustic soda concentration on mass loading of activated carbon on yarns and the related capacitance output of the designed yarn supercapacitor.

They are being actively used in fields as varied as biology, social networks, cybersecurity, and computer networks. At the same time, graph problems have some properties such as irregularity and poor locality that make their performance different than regular applications performance. Therefore, parallelizing graph algorithms is a hard and challenging task. Initial evidence is that standard computer architectures do not perform very well on graph algorithms. Little is known exactly what causes this. The Graph500 benchmark is a representative application for parallel graph-based computations, which have highly irregular data access and are driven more by traversing connected data than by computation. In this paper, we present results from analyzing the performance of various example implementations of Graph500, including a shared memory (OpenMP) version, a distributed (MPI) version, and a hybrid version. We measured and analyzed all the factors that affect its performance in order to identify possible changes that would improve its performance. Results are discussed in relation to what factors contribute to performance degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graph%20computation" title="graph computation">graph computation</a>, <a href="https://publications.waset.org/abstracts/search?q=graph500%20benchmark" title=" graph500 benchmark"> graph500 benchmark</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20architectures" title=" parallel architectures"> parallel architectures</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20programming" title=" parallel programming"> parallel programming</a>, <a href="https://publications.waset.org/abstracts/search?q=workload%20characterization." title=" workload characterization."> workload characterization.</a> </p> <a href="https://publications.waset.org/abstracts/133666/analyzing-the-factors-that-cause-parallel-performance-degradation-in-parallel-graph-based-computations-using-graph500" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133666.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">147</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">14957</span> Incorporation of Coarse Rubber Aggregates in the Formulation of Self-Compacting Concrete: Optimization and Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zaoiai%20Said">Zaoiai Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Makani%20Abdelkadir"> Makani Abdelkadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tafraoui%20Ahmed"> Tafraoui Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete material suffers from a relatively low tensile strength and deformation capacity is limited. Such defects of the concrete are very fragile and sensitive to shrinkage cracking materials. The Self- Compacting Concrete (SCC) are highly fluid concretes whose implementation without vibration. This material replaces traditional vibrated concrete mainly seen techno-economic interest it presents. The SCC has several advantages which are at the origin of their development crunching. The research is therefore to conduct a comparison in terms of rheological and mechanical performance between different formulations to find the optimal dosage for rubber granulates. Through this research, we demonstrated that it is possible to make different settings SCC composition having good rheological and mechanical properties. This study also showed that the substitution of natural coarse aggregates (NA) by coarse rubber aggregates (RA) in the composition of the SCC, contributes to a slight variation of workability in the fresh state parameters still remaining in the field of SCC required by the AFGC recommendations. The experimental results show that the compressive strengths of SCC decreased slightly by substituting NA by RA. Finally, the decrease in free shrinkage is proportional to the percentage of RA incorporated into the composition of concrete. This reduction is mainly due to the improvement of the deformability of these materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title="self-compacting concrete">self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=coarse%20rubber%20aggregate" title=" coarse rubber aggregate"> coarse rubber aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=rheological%20characterization" title=" rheological characterization"> rheological characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20performance" title=" mechanical performance"> mechanical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a> </p> <a href="https://publications.waset.org/abstracts/41932/incorporation-of-coarse-rubber-aggregates-in-the-formulation-of-self-compacting-concrete-optimization-and-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41932.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">287</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">14956</span> Improving the Gain of a Multiband Antenna by Adding an Artificial Magnetic Conductor Metasurface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Bousselmi">Amira Bousselmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a PIFA antenna designed for geolocation applications (GNSS) operating on 1.278 GHz, 2.8 GHz, 5.7 GHz and 10 GHz.

The key characterization techniques employed are the synchrotron X-ray Absorption Spectroscopy (XAS) combined with X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to obtain a more holistic approach to understanding material properties. This research effort provides additional battery characterization knowledge that promotes the development of new cathodes, anodes, electrolyte and separator materials for batteries, hence, leading to better and more efficient battery performance. Both ex-situ and in-situ synchrotron experiments were performed on LiFePO₄, one of the most common cathode material, from different commercial sources and their structural analysis, were conducted using Athena/Artemis software. This analysis technique was then further extended to study other cathode materials like LiMnxFe(₁₋ₓ)PO₄ and even some sulphate systems like Li₂Mn(SO₄)₂ and Li₂Co0.5Mn₀.₅ (SO₄)₂. XAS data were collected for Fe and P K-edge for LiFePO4, and Fe, Mn and P-K-edge for LiMnxFe(₁₋ₓ)PO₄ to conduct an exhaustive study of the structure. For the sulphate system, Li₂Mn(SO₄)₂, XAS data was collected at both Mn and S K-edge. Finite Difference Method for Near Edge Structure (FDMNES) simulations were also conducted for various iron, manganese and phosphate model compounds and compared with the experimental XANES data to understand mainly the pre-edge structural information of the absorbing atoms. The Fe K-edge XAS results showed a charge compensation occurring on the Fe atom for all the differently synthesized LiFePO₄ materials as well as the LiMnxFe(₁₋ₓ)PO₄ systems. However, the Mn K-edge showed a difference in results as the Mn concentration changed in the materials. For the sulphate-based system Li₂Mn(SO₄)₂, however, no change in the Mn K-edge was observed, even though electrochemical studies showed Mn redox reactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=li-ion%20batteries" title="li-ion batteries">li-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry"> electrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20absorption%20spectroscopy" title=" X-ray absorption spectroscopy"> X-ray absorption spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a> </p> <a href="https://publications.waset.org/abstracts/98710/advanced-structural-analysis-of-energy-storage-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98710.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">150</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">14954</span> Chemical and Mechanical Characterization of Composites Reinforced with Coconut Fiber in the Polymeric Matrix of Recycled PVC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luiz%20C.%20G.%20Pennafort%20Jr.">Luiz C.

PVA solution which was also modified by using alkoxy silanes, in order to prevent the scaffolds from being damaged by aqueous cell medium, was added. Keratin was dissolved and then added into the electrospinning solution. Keratin containing 4-VBBA- HAP/PVA composite was used to fabricate nanofiber scaffolds with the simultaneous UV-reactive electrospinning technique. The structural characterization was done by FT-IR. Thermal gravimetric analysis was also performed by using TGA. The morphological characterization was determined by SEM analyses. Our second aim was to create a scaffold where cells could grow. With this purpose, suitable nanofibers were choosen according to their SEM analysis. Keratin containing nanofibers were seeded with 3T3, ECV and SAOS cells and their cytotoxicity and cell proliferation were investigated by using MTT assay. After cell culturing process morphological characterization was determined by SEM analyses. These scaffolds were designed to be nontoxic biomaterials. Here, a comparision was made between keratin containing 3T3, ECV and SAOS seeded nanofiber scaffolds and the results were presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title="cell culture">cell culture</a>, <a href="https://publications.waset.org/abstracts/search?q=keratin" title=" keratin"> keratin</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=UV-reactive%20electrospinning" title=" UV-reactive electrospinning"> UV-reactive electrospinning</a> </p> <a href="https://publications.waset.org/abstracts/25095/uv-reactive-electrospinning-preparation-characterization-and-cell-culture-applications-of-nanofiber-scaffolds-containing-keratin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25095.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">454</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">14952</span> Mechanical Characterization and Metallography of Sintered Aluminium-Titanium Diboride Metal Matrix Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sai%20Harshini%20Irigineni">Sai Harshini Irigineni</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Kumar%20Reddy%20Narala"> Suresh Kumar Reddy Narala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The industrial applicability of aluminium metal matrix composites (AMMCs) has been rapidly growing due to their exceptional materials traits such as low weight, high strength, excellent thermal performance, and corrosion resistance. The increasing demand for AMMCs in automobile, aviation, aerospace and defence ventures has opened up windows of opportunity for the development of processing methods that facilitate low-cost production of AMMCs with superior properties. In the present work, owing to its economy, efficiency, and suitability, powder metallurgy (P/M) technique was employed to develop AMMCs with pure aluminium as matrix material and titanium diboride (TiB₂) as reinforcement. AMMC samples with different weight compositions (Al-0.1%TiB₂, Al-5%TiB₂, Al-10%TiB₂, and Al-15% TiB₂) were prepared through hot press compacting followed by traditional sintering. The developed AMMC was subjected to metallographic studies and mechanical characterization. Experimental evidences show significant improvement in mechanical properties such as tensile strength, hardness with increasing reinforcement content. The current study demonstrates the superiority of AMMCs over conventional metals and alloys and the results obtained may be of immense in material selection for different structural applications. <p
