| Abstract Scope |
Fabrication of intricate, additive manufactured structures using multi-material compositions presents challenges with respect to both the transition between materials and this interfacial strength. The research work presented here investigates a new metal powder binning approach for creating such multi-material components, which are produced a standard EOS M290 machine. The influences on interfacial quality of different scan strategies applied to the interface zone are probed for multi-material component specimens comprised of: 1) Inconel 625 bonded to Inconel 718; 2) Inconel 625 bonded to 316 stainless steel, and 3) Inconel 718 bonded to 316 stainless steel. Compared to alternate multi-material methods, the tensile strength of specimens with interface zones situated in the gage section were found to be superior in nearly all cases. |
