| Abstract Scope |
Duplex stainless steel (DSS) 2209 is critical in naval applications due to its excellent corrosion resistance properties. The Wire-Arc Additive Manufacturing (WAAM) process can produce large-scale components with minimal wastage and high deposition rates. This study examines the process-microstructure-property relationships in WAAM of DSS 2209, focusing on the effects of build height, spatial location (edge/central), and sample orientation (horizontal/vertical). Metallography and tensile samples were extracted from the top, middle, and bottom regions of wall, with additional metallography samples extracted near the substrate. Optical microscopy indicated uniform microstructure, while EBSD analysis revealed consistent phase content among the edge/central region samples. Samples extracted from near substrate regions had comparatively lower microhardness. Tensile testing revealed that vertical samples had lower strength but higher total elongation than horizontal samples. These insights are vital for optimizing the stability and performance of WAAM DSS 2209 components for large scale structural applications. |
