Effect of energy density on cracking of ZGH451 superalloy by laser powder bed fusion

ZGH451 is a novel age-strengthened nickel-based superalloy renowned for its exceptional toughness and corrosion resistance. However, it is susceptible to cracking during laser powder bed fusion (LPBF) processing. This study systematically investigates LPBF-fabricated ZGH451 to establish the inherent...
