Effect of heat treatment on microstructure evolution and strengthening-toughening behavior of high-strength Mg-Gd-Y-Zn-Zr alloy fabricated by wire-arc additive manufacturing

Mg-Gd-Y-Zn-Zr alloy is an important lightweight material in the aerospace field. Wire arc additive manufacturing (WAAM) provides a new route to fabricate large Mg alloy components. Here, a Mg-8Gd-4Y–1Zn-0.5Zr (wt.%) alloy was fabricated using WAAM based on the cold metal transfer (CMT) process. Subs...
