摘要：
The active energy and constitutive equations of magnesium alloys formed under different conditions were reviewed. The superplastic characteristics of coarse and fine-grained magnesium alloys were summarized. Then the ways of superplastic deformation were briefly analyzed. The results show that the development trend of superplastic magnesium alloys has been advanced remarkably and will be developed rapidly in the future. Obtaining high-strain rate and low-temperature superplastic magnesium alloys, deducing cost, safety and environmental protection are the researching focuses nowadays.
