The dual role of Mg in LPBF-processed high-strength AlMnScZr alloys: strengthening and thermal softening mechanisms

The dual roles of Mg in the room-temperature strengthening and high-temperature softening of LPBF-Processed AlMnScZr alloys are systematically elucidated. The addition of Mg promotes compositional supercooling during solidification, transforming the as-built columnar grains of the Mg-free alloy into...
