Solidification microstructure and elemental segregation in laser-based powder bed fusion additively manufactured IN738LC Ni-based superalloy

We systematically investigate the solidification microstructure and elemental segregation in Inconel 738LC fabricated via laser-based powder bed fusion of metals (PBF-LB/M) under three representative process conditions. Microstructural characterizations confirm a strong correlation between thermal i...
