Abstract Scope |
Haynes 282 is a nickel-based gamma-prime strengthened superalloy with the unique combination of creep strength, thermal stability, and weldability among other desirable properties making it a great candidate for advanced ultra-supercritical applications. Wire arc additive manufacturing (WAAM) can be used to produce large metallic parts with high deposition rates holding potential for large-scale additive manufacturing applications using weldable metal alloys in wire form. By coupling high-throughput experiments and ICME (Integrated Computational Materials Engineering) modeling, the post-heat treatment impact on microstructure-property relationships have been studied, including precipitation strengthening effect, and oxidation behavior of WAAM Haynes 282 under different heat treatment conditions. This study explores an effective pathway to further enhance the mechanical performance of alloy components prepared by WAAM. |
