Influence of post-heat treatments on the microstructure and mechanical properties of Inconel 738 produced by laser directed energy deposition

Influence of post-heat treatments on the microstructure and mechanical properties of Inconel 738 produced by laser directed energy deposition

In this paper, the non-weldable precipitation-hardened superalloy Inconel 738 thin-wall parts were fabricated by laser directed energy deposition (LDED). The influence of post heat treatments including solution and aging heat treatments on the microstructures and mechanical properties of LDED-manufa...
