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.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, close loop recycled aluminium alloys can be adversely affected by impurities and alloying elements present in the recycled feedstock. In this study, the influence of three composites, namely alumina (Al2O3), ferric oxide (Fe2O3), and manganese (Mn), on the properties of recycled aluminium taldon scraps was investigated to enhance the tensile behaviour of the alloys. The effects of these composites on the mechanical properties, microstructure, and corrosion behaviour of the recycled aluminium alloys were evaluated through experimental characterization techniques. The results showed that the addition of these composites had a significant influence on the properties of recycled aluminium alloys, providing insights into the potential for improving the performance of recycled aluminium alloys through composite additions. The addition of Al2O3 enhanced the tensile strength by 44.18 % and the variation can be attributed to the strengthening of the dendritic zones by the formation of α-Al.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140687756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increase in demand and decrease in availability of fine aggregates, we use an alternative material called quarry dust, it is a finer material generated from stone quarries. This paper deals with the feasibility study on the utilization of quarry dust as a partial replacement in fine aggregate. In this experimental investigation, the properties of materials are tested as per Indian standards. The filling ability, passing ability and flowability characteristics of SCC as a partial replacement of fine aggregate with quarry dust was investigated as per EFNARC guidelines. In this experimental investigation, different mixes were prepared as a partial replacement of fine aggregate with quarry dust at various percentages such as 10%, 20%, 30%, 40% and 50% to obtain the optimum replacement level. The Slump flow, U-box, L-Box, V-Funnel and J-ring tests were carried out to determine the workability of SCC. The finding shows that the workability decreases with the addition of quarry dust. It is concluded that addition of quarry dust reduces the fresh properties of the SCC.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Al Rashed, Shad Inquiad Mim, Bijoy Mallick","doi":"10.4028/p-pi1yt2","DOIUrl":"https://doi.org/10.4028/p-pi1yt2","url":null,"abstract":"Magnesium alloys have spurred a strong interest in automobile and aerospace industries owing to their high specific strength and stiffness, with magnesium being the lightest structural metal. 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 10-4 s -1 strain rate and at 3000C, 3500C, 4000C, and 4500C temperature under 5 x 10 -4 s -1 strain rate. According to XRD investigation, the alloys essentially comprise the Ca-containing phase and Mg2Sn 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.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kulkarni","doi":"10.4028/p-oqdeq5","DOIUrl":"https://doi.org/10.4028/p-oqdeq5","url":null,"abstract":"SS316L is an austenite-grade steel material offering a better strength-to-ductility ratio, higher corrosion resistance, and biocompatibility. 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.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140685885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
