Wire-arc additive manufacturing and post-heat treatment optimization on microstructure and mechanical properties of Grade 91 steel

Wire-arc additive manufacturing (WAAM) of Grade 91 steel (P91) is demonstrated for the first time. This alloy has been widely used in pressure vessel components of thermal and nuclear power plants. The post-WAAM heat treatment process is critical to the anisotropy elimination and property improvemen...
