Effects of heat treatment on structure-property relationships of additively manufactured Inconel 718, The
To date, standard heat treatments (SHTs) for cast and wrought (C&W) conditions have been utilized for additively manufactured (AM) materials. However, it is known that AM processes induce high thermal gradients and rapid cooling rates that produce fundamentally different microstructure consisting of hierarchical features, epitaxial grain growth, and strong crystallographic fiber texture with respect to the build direction. Since these microstructures differ from their C&W forms, their reactions to SHTs should be inherently different as well. Understanding these differences is vitally important ...
