摘要：

The maximum strain rate sensitivity coefficient is obtained theoretically from the material parameters that describes the constitutive equation of superplastic materials. This m-value correspond to a specific strain rate and are investigated as a function of those parameters. The variation of the strain rate sensitivity m with strain rate is also shown. The new constitutive equation for superplasticity is used.
