A high-strength, heat-resistant Al–5.7Ni eutectic alloy with a Zr–induced bimodal grain structure fabricated by laser powder bed fusion
Eutectic Al–Ni alloys are attractive for laser powder bed fusion (LPBF) because their narrow solidification range reduces susceptibility to solidification cracking. In this study, a high-strength, heat-resistant Al–Ni–Zr alloy was fabricated by LPBF using blended Al–5.7Ni and ZrH2 powders. The composition of the as-bui...
