Abstract

The mechanical properties of deformed AZ31 Mg alloy at high temperature of 450–600°C with a strain rate of 3s−1 were investigated by tensile tests. The zero strength of AZ31 Mg alloy was emerged at a mushy state (600°C), while the zero ductility was appeared at 575°C, just below the solidus temperature. The abnormal coarsening of the grains happened at the
