| Abstract Scope |
Bimetallic additive manufacturing offers the ability to leverage beneficial material properties from a variety of alloys. Unique component design combinations are possible that minimize drawbacks inherent to the monolithic alloys. Thus the component performance is enhanced as compared with traditional fabrication methods using monolithic materials. However, a key drawback of these additive techniques is the unknown characteristics of the resulting interfacial mixing zone, which depend on a combination of material chemistry and additive process used. In this study, two bimetallic components were made from Inconel 625 and GRCop-42. The GRCop-42 was printed using L-PBF to form the substrate. Two processes were used to deposit Inconel 625 onto the GRCop, LP-DED and AW-DED. The resulting interface was evaluated using qualitative metallographic techniques and miniature tensile testing. Supporting solidification models were used to determine potential detrimental phase formations that can occur as elements segregate during the rapid solidification of each AM process. |
