Abstract The homogenized Mg-11Gd-3Y-xZn-0.5Zr(x=0, 0.3, 0.7, 1.5, mass fraction/%) alloy was subjected to a hot compression experiment at temperature of 350—500 ℃ and strain rate of 0.002—1 s^-1. The microstructure of the alloy was analyzed. The thermal deformation activation energy was established and the thermal processing map of the alloy was established and analyzed. The results showed that the thermal deformation and dynamic recrystallization of Mg-11Gd-3Y-xZn-0.5Zr alloy occur. The peak stress increases with the increase of Zn content. The flow stress increases with the increase of temperature or decreases of strain rate. When the strain is less than 0.4, the flow stress increases with the increase of Zn content. When the strain reaches 0.4, the flow stress increases first and then decreases with the increase of Zn content. When the Zn content is 0.7%, the flow stress reaches the maximum value. The addition of Zn (0.3%) can significantly improve the thermal deformation activation energy of the alloy, but further increase the Zn(0.3%—1.5%) has little effect on the activation energy of the alloy. The hot working process range of the alloy is determined by the thermal processing map. Zn can reduce the range of instability zone, slow down the alloy recrystallization process and refine the alloy structure. When the Zn content is 0.7%, the hot working effect is the best.
