Hot tensile deformation behaviors and a fracture damage model of the Mg-Gd-Y-Zn-Zr alloy

Journal of Materials Research and Technology, 2022
In this study, the hot deformation of Mg-9Gd-4Y-2Zn-0.5Zr alloy was studied by the hot tensile test conducted at various temperatures (350°C–500 °C) and strain rates (0.0001–0.1s−1).
