Abstract Scope |
Duplex stainless steel (DSS) 2209 has been widely used in naval applications due to its excellent corrosion resistance and mechanical properties. The Wire-Arc Additive Manufacturing (WAAM) process is gaining traction in the naval sector for its ability to produce large-scale components with minimal material wastage and high deposition rate. The present study delves into the influence of build height, scan direction (edge/middle), and sample orientation (horizontal/vertical) on the microstructural characteristics and mechanical properties of WAAM DSS 2209. Metallography and tensile samples were extracted from the top, middle, and bottom regions of wall, with additional metallography samples extracted near the substrate regions. Optical micrographs revealed a uniform microstructure while EBSD analysis revealed varying phase content among the edge samples and consistent austenite content in the middle samples along the build. Such comprehensive analysis can provide valuable insights into optimizing the performance and reliability of WAAM-deposited DSS 2209 components for naval applications. |
