Paper Title:
Superplastic Forming Limit and Instability of AZ31B Sheet
  Abstract

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 2=0. The superplastic forming limit diagram(FLD) at 573K and 3.3×10-4S-1 was established for the first time.
