Hot isostatic pressing elimination of process-induced defects in laser powder bed fusion fabricated DZ125 superalloy: Microstructure evolution and mechanical property enhancement

Hot isostatic pressing elimination of process-induced defects in laser powder bed fusion fabricated DZ125 superalloy: Microstructure evolution and mechanical property enhancement

This study systematically investigated the crack formation mechanisms in DZ125 nickel-based superalloy fabricated by laser powder bed fusion (LPBF) and evaluated the effectiveness of hot isostatic pressing (HIP) in defect elimination, microstructural modification, and mechanical property enhancement...
