Forming quality, microstructure, and ductility-oriented mechanical performance of laser powder bed fusion processed Ni-based superalloy using different thermal input modes

Forming quality, microstructure, and ductility-oriented mechanical performance of laser powder bed fusion processed Ni-based superalloy using different thermal input modes

Thermal input modes significantly affect forming quality, microstructure, and mechanical properties of components fabricated by laser powder bed fusion (LPBF). However, their influence on GH4169 Ni-based superalloy remains inadequately characterized. This study systematically investigates five therm...
