Enhanced strength and ductility in Mg-9Gd-4Y–2Zn-0.5Zr alloy under high-temperature compression enabled by the LPSO phase

Two thermomechanical treatments, namely N (510 °C/16 h) and C (510 °C/16 h + 480 °C/8 h), were employed in an extruded Mg-9Gd-4Y–2Zn-0.5Zr alloy to reveal the influence mechanism of coordinated deformation of the 14H-LPSO phase during the hot deformation process. Results revealed that the C-treated...
