| Abstract Scope |
Powder bed metal additive manufacturing (PBAM) techniques have now reached the point where complex near-net shaped components can be manufactured from powders of a wide variety of alloys. For PBAM, only one material can be used with available equipment for a build. Using a new research PBAM system with a dual-feed hopper, this study examines the additive manufacturing of components with layers of two different materials. Model bilayer samples of 17-4 PH stainless steel and pure copper have been produced using this research AM system. Interfacial microstructures and phases obtained from the PBAM process have been compared with those of 17-4 PH / Cu diffusion couples. This allows purely chemical interactions to be distinguished from the effects of the PBAM process. The use of more than one alloy in PBAM can potentially lead to the manufacturing of complex components with local variations in materials and properties. |
