Effect of layer thickness, and laser energy density on the recrystallization behavior of additively manufactured Hastelloy X by laser powder bed fusion

A single-phase Ni-superalloy (Hastelloy X) was fabricated by laser powder bed fusion (L-PBF) using different layer-thicknesses (i.e., 40, 60, 80, and 120 µm), by implementing different optimized volumetric laser energy densities (i.e., VED of 67, 44, 31, and 35 J/mm3). As-built (AB) microstructure,...
