Superplastic forming limit and instability of AZ31B sheet

摘要：

The superplastic bulging test of AZ31B magnesium alloy sheet of 0.6mm thick was carried out on Alliance RT/50 tensile machine at 573K and 3.3×10-4S-1. It is found that either in tensile-compressive deformation or in bi-axis tensile deformation, the judgment criterion for local necking of superplastic deformation is dε2=0. The superplastic forming limit diagram (FLD) at 573K and 3.3×10-4S-1 was established for the first time.
