Microstructure and mechanical properties of NiTi-SS bimetallic structures built using Wire Arc Additive Manufacturing

Dissimilar joining of Nickel-titanium (NiTi) alloy with other metallic alloys can be used to widen the applications of NiTi for developing artificial bones and joints, guidewires, and stents. This paper presents the microstructure and mechanical properties of Wire Arc Additive Manufactured NiTi-SS bimetallic structures for the first time. Defect-free deposit with a smooth transition in the composition across the joint is observed. NiTi shows a...
