Duplex stainless steel (DSS) has a biphasic microstructure ideally consisting of 50% austenite (γ) and 50% ferrite (δ). Metal Additive Manufacturing (MAM) has emerged rapidly and received substantial attention from last decade. Wire arc Additive Manufacturing (WAAM) and Laser-Direct Energy Deposition (L-DED) are some of the major DED processes leveraged for depositing metallic material using focused thermal energy resulting into near-net shape products and refurbishment of worn out parts. One of the major challenges in depositing DSS is to understand the complex thermal history which creates difficulty in achieving balanced ferrite-austenite ratio. Consequently, it will impact on the microstructure, mechanical and corrosion properties of deposited parts. In this research, we are working on revealing the major differences in process-microstructure-property relationship due to variation in heat energy and feedstock type to develop strategies for next generation hybrid AM process development in mission critical defense applications.
