摘要：
The hot compression deformation of Mg-12Gd-2.5Nd-0.5Zr heat-resistant magnesium alloy was carried out on Gleeble-1500D thermo-mechanical simulator with the strain rate range of 0.002-1 s(-1), the deformation temperature range of 623-773 K and maximum strain of 50 %. The results show that true stress decreases with the increase of deformation temperature at a constant strain rate, and the true stress increases with the increase of strain rate at a same temperature. The deformation constitutive equation was established, and the hot deformation activation energy of 292.679 kJ/mol is determined.
