| Abstract Scope |
Wire+arc additive manufacturing (WAAM) technology adopts existing arc welding equipment and consumables to fabricate a part additively depositing metal in near net shape. High deposition rate, a large selection of materials, low material and equipment costs and adequate structural integrity are some characteristics of the WAAM process. In addition, WAAM technology can deposit more than one metal simultaneously or subsequently to have a combination of complementary material properties within the same structure along with cost optimization. In this work, integral bimetallic additively manufactured structures (BAMS) of two materials namely austenitic stainless steel and Inconel 625 was successfully deposited. A gradient of microstructure, hardness, and composition was observed at the interface for both structures. Microstructure, elemental composition, and mechanical properties were characterized and discussed. The study demonstrates the suitability of WAAM process to fabricate the multi-functional component as an integral part. |
