| Abstract Scope |
Duplex stainless steels (DSS) are two-phase corrosion resistant alloys of ideally equal amounts of austenite and ferrite that are commonly used in the marine industry. While DSS alloys are commonly forged or cast, additive manufacturing (AM) can allow for near net shaping and complex geometries. Wire-arc AM (WAAM) is a promising technique with high deposition rates and large build volumes. While the most common DSS wrought alloy is 2205, the only commercially available DSS wire is ER2209 (a common feedstock for the welding community). This work will be one of the first to showcase a successful AM build using 2205 wire. The microstructure of two WAAM builds, namely 2205 and 2209, will be compared. Further characterization will include tensile and microhardness data, as well as the effect of wall thickness, location, and composition on mechanical properties. This work will serve as a continuation for microstructure-property relationships in WAAM DSS alloys. |
