In-Situ Alloy Formation During Selective Laser Melting with CuSn10 and Aluminum Powders

Abstract

Thanks to metal additive manufacturing (AM)Additive manufacturing (AM), the way metal parts are made has changed in recent decades. Almost unlimited designs are possible, and local material properties such as microstructural properties can be realized through regional process variations. Although many scientists and engineers have worked and are working on AM and their efforts have led to the commercialization of AMAdditive manufacturing (AM) metal technologies, the effort required to create new and customized alloys is still high. This is due to the fact that a completely created alloy has to be brought into the powdered initial form before it can be manufactured, which involves quite a lot of effort. In-situ alloys can remedy this situation by mixing powder particles of different materials with each other before production and the actual target material is only created during the production process when it is melted by the laser beam. This paper gives a brief overview of the in-situ alloyingIn-situ alloying of a CuAl12Sn9 alloy by selective laser meltingSelective laser melting of CuSn10 and pure aluminum powder.
