Metal 3D printing is becoming invaluable for many manufacturers today worldwide, and the research regarding processes and materials continues as researchers from both Singapore Institute of Manufacturing Technolog y and Nanyang Technological University explore metal powders being used in electron beam melting (EBM) technology today in ‘ Additively manufactured CoCrFeNiMn high-entropy alloy via pre-alloyed powder .’ Most studies regarding serious manufacturing practices and their interest in 3D printing with metal center around the best ways to produce strong, complex geometries. Here, the authors review whether CoCrFeNiMn high entropy alloy (HEA) parts produced through EBM—very similar to the popular selective laser sintering (SLS) process—is a realistic improvement over conventional casting techniques. CoCrFeNiMn is known as an equiatomic alloy powder made through vacuum induction via atomization with argon gas. As a single face-centered-cubic (FCC) crystal structure, CoCrFeNiMn has been the focus of a wide variety of research throughout the years due […]
