| Abstract Scope |
The wire+arc additive manufacturing process is fitted to fabricate bimetallic additively manufactured structures (BAMS) and have a combination of complementary properties in a single component. The BAMS often have different properties compared to the wrought parent materials, hence, heat treatment might require to attain desired properties. In this work, BAMS of low carbon steel and austenitic stainless steel was heat-treated with varied heat treatment conditions to improve the mechanical integrity of the part. Changes in the microstructure, strength, elongation, and failure location along with compositional gradient and hardness were observed followed by the heat treatment of the BAMS. The microstructure and elemental composition were characterized to justify the change in mechanical properties and the failure location of the BAMS. Based on the results, this study justifies the heat treatment of BAMS and suggests the optimum heat treatment conditions for the mentioned BAMS. |
