Abstract The homogenized Mg-11Gd-3Y-1.1Zn-0.5Zr alloy was subjected to the hot compression experiment with the temperature of 350—500℃ and the strain rate of 0.002—1 s^-1 using a Gleeble-1500 thermal simulator. The constitutive equation of high temperature plastic deformation was established and analyzed. The results showed that the dynamic recover and dynamic recrystallization of Mg-11Gd-3Y-1.1Zn-0.5Zr alloy occurred, and the flow stress of the alloy increased with the increase of temperature and strain rate. The thermal deformation activation energy of the alloy was about 286.134 kJ/mol; the regional energy dissipation rate of the alloy at T=380—500℃, ε·=0.002—0.05 s^-1 was greater than 30% and no instability, which indicates that the alloy is suitable for thermal processing.
