Microstructure and mechanical properties of mild steel-stainless steel bimetallic structures built using Wire Arc Additive Manufacturing

The integration of manufacturing solutions based on the use of direct energy deposition technologies, in-cluding Wire Arc Additive Manufacturing WAAM, enables partial solutions using bimetallic materials that improve the final in-use properties of the part. In this paper, the fabrication of bi-metallic steel with mild steel-stainless steel in both overlapping and superimposed solutions is experimentally presented. The defect-free fabrication of bi-metallic walls from different steels is a unique process that is presented here for the first time. (c) 2022 CIRP.
