Titanium and its alloys have a wide range of applications in various industries, including medicine. However, the low strength and high friction coefficient hinder their development in contact friction due to fretting fatigue. Among many factors, structure refinement, temperature and amplitude are the most responsible for fretting wear of structural materials. The purpose of the article is to investigate the effect of displacement amplitude, size of grain and test temperature on the fretting wear of the pure titanium in coarse-grained and ultrafine-grained states. It is shown that an increase in the test temperature for both structural states leads to a multiple increase in wear. Structural refinement of titanium to hundreds of nanometers helps to reduce wear at room and elevated temperatures. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601582', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 3 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1120.11">Effect of Addition of Sn on High-Temperature Tensile Strength of Rare-Earth Free Mg-1Ca Alloy</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: H.M.

Alloying with rare earth improves tensile properties considerably. However, the availability of rare-earth elements is a concern. Therefore, attempts are being made to prepare alloys without rare-earth elements. One Mg-1Ca alloy was prepared with different amounts of Sn to study the impact on the high-temperature strength after dynamic recrystallization by hot rolling. Optical and electron microscopy analyzed the change in the microstructure. XRD and EDS were used to identify phases and composition of different microconstituent particles and high-temperature strength was measured at 250°C, 300°C, and 350 °C under 2 x 10<sup>-4 </sup>s <sup>-1</sup> strain rate and at 3000C, 3500C, 4000C, and 4500C temperature under 5 x 10 <sup>-4</sup> s <sup>-1 </sup>strain rate. According to XRD investigation, the alloys essentially comprise the Ca-containing phase and Mg<sub>2</sub>Sn particles. The Mg-1Ca-1Sn alloy exhibited maximum high-temperature strength at 250°C, attributed to the maximum amounts of MgCaSn particles. It was also found that dynamic recrystallization was accelerated by particle-stimulated nucleation and maximum refinement was found at 1% Sn-containing alloys. </div> <div> <a data-readmore="{ block: '#abstractTextBlock603212', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1120.21">Comparison of Static and Dynamic Mechanical Response of Aluminum 6061 Subjected to Multi-Directional Forging</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Burak Bahat, Guney Guven Yapici </div> </div> <div id="abstractTextBlock602323" class="volume-info volume-info-text volume-info-description"> Abstract: The present investigation focuses on the implementation of the multi-axial forging process, recognized as a severe plastic deformation (SPD) technique, with the aim of elevating the mechanical features of the widely employed Al 6061 alloy. Specifically utilized in the automotive and aviation industries, this alloy's behavior was meticulously examined through a series of quasi-static and dynamic tests. To achieve this objective, the multi-directional forging (MDF) process was implemented for up to three cycles, involving a total of nine passes, at a raised temperature of 200 °C. Subsequently, the severely deformed material underwent utilizing high strain rate loading for the Split Hopkinson Pressure Bar (SHPB) test system. After MDF, the grain size is refined down to below 11 microns with a starting grain size of 13 microns. This is reflected as increased hardness and yield strength in the quasi-static regime. For SHPB characterization, increased dynamic strength is also observed. However, although the yield strength showed about 60% increase with decent ductility, the maximum dynamic strength increased about 10% after SPD with a relatively brittle behavior. </div> <div> <a data-readmore="{ block: '#abstractTextBlock602323', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 21 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1120.29">A Comprehensive Review on the Effect of Thermal Post Processing on DMLS Processed SS316L Components</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Purushottam Balaso Pawar, Swanand G.

In DMLS products, residual stresses are inevitable because of the thermal gradient involved in the process and the porosity that results from process limitations. As a result of these defects, the strength of the product is reduced and the quality of the product is compromised. The primary objective of this article is to offer an in-depth analysis of different heat treatment methods that are employed to achieve superior properties in products manufactured through DMLS processing. Thermal processing techniques include Hot Isostatic Pressing, Solution Heat Treatment, T6 heat treatment, Direct Aging Treatment, etc. Using thermal post-processing techniques, 99.99% of the porosity is eliminated, corrosion resistance is significantly increased, and mechanical properties are enhanced. This study examines the need for thermal post-processing, the methodology employed, and the property enhancements achieved by DMLS products. There are many factors affecting thermal post-processing, however, efforts have been made to review the details regarding thermal post-processing applied to SS316L material processed with direct metal laser sintering. Moreover, the specific methods for post-processing can be determined based on the product's intended application. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601699', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 29 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1120.43">Multi Objective Optimization of Turning Operation Parameters for Aluminium Alloy Using Grey Relational Analysis Method</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Bhanodaya Kiran Babu Nadikudi </div> </div> <div id="abstractTextBlock601737" class="volume-info volume-info-text volume-info-description"> Abstract: In high strength aluminium alloy material turning operation, high material removal and good surface are desirable output characteristics.

Despite being adaptable, the procedure currently works with a restricted number of materials, mostly thermoplastic polymers. 3D printing fused deposition modeling (FDM) provides opportunities to produce complex components relatively quickly in small batch with a high degree of flexibility for both manufacturer and researcher. Process parameters in FDM like infill pattern, infill density, printing speed, raster angle influences the mechanical properties of a printed parts. In this research study, a novel approach on the internal structure of 3D printed parts say combined infill pattern (Triangles & Octet) on a single part has been introduced and mechanical properties like tensile test, flexural strength, compression strength and hardness were measured. Specimens were printed in Acrylonitrile butadiene styrene (ABS) as per ASTM standards by FDM technology with different infill densities of 60%, 80% and 100% by XY build orientation. SEM analysis was made to analyze the morphological and inter bonding of different infill patterns. The results show that mechanical performance was inflated by an increase in infill density. </div> <div> <a data-readmore="{ block: '#abstractTextBlock600858', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 61 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1120.69">Development of Brake Pad Using Palm Kernel Shell Reinforcement Polymer Composite</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: V.P.

Research on agricultural by - products such as flax fibres, rockwool, aramid fibres, banana fibres, and nut shells from palm trees have been used to develop a number of potential replacements for asbestos. Palm wastes, which are picked for the study since there was a paucity of previous research on the topic, are obtained from agricultural waste fibres. As part of this investigation, a composite material was created, and a number of tests were carried out in order to investigate the wear and durability of a set of unique composites. The novel composites contained 20% epoxy resins, 10 % carbon, 15% CaCO<sub>3</sub>, 30–45% PKS, and 10–25%Al<sub>2</sub>O<sub>3</sub> respectively.

Prominent reviews have indicated a heavy dependence on PLA polymer for fused deposition Modeling (FDM) based studies. To promote biodegradability, the effect of natural fibres as reinforcement has been widely researched in the literature. However, it is noted that discontinuous natural fibre reinforcement yields negative or negligible improvement in the strength and modulus of FDM-based biocomposites. Hence, an attempt to hybridise FDM with a conventional composite manufacturing method was made in this study by cladding natural fibre reinforcement over FDM-based polymer. Tensile and flexural test coupons were additively manufactured by FDM and reinforced with a skin of bi-directional woven basalt fibre through compression moulding. A 90% improvement in tensile strength and a similar significant increase in flexural strength was observed. Further, an average increment of 46.38% and 237.24% in tensile and flexural modulus, respectively, was achieved through this manufacturing technique. In conclusion, a drastic improvement in mechanical performance can be obtained through the hybridisation of manufacturing methods and needs further investigation towards the compatibility of adhesive materials with FDM polymers. </div> <div> <a data-readmore="{ block: '#abstractTextBlock600977', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 77 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 18 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/MSF.1120/2">2</a></li><li class="PagedList-skipToNext"><a href="/MSF.1120/2" rel="next">></a></li></ul></div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy & Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/read-and-publish-agreements">Read & Publish Agreements</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> © 2024 Trans Tech Publications Ltd.
