In this paper, the influence of temperature and strain rate on the superplastic deformation behaviors of the Mg-Zn-Nd alloy has been investigated through performing tensile tests at different temperatures and strain rates. After 4 passes of ECAP by route C, the strain-rate sensitivity coefficients reached 0.32 at 300°C, indicating that the ECAPed Mg-Zn-Nd alloy exhibited a good superplasticity at lower temperature. The results of flow activation energy showed that the super-plastic deformation mechanism of magnesium alloys is grain-boundary sliding controlled by grain boundary diffusion.
