| Abstract: | Taking the cavitation in materials as a form of structural evolution, wemake firstly a discussion on the effect of cavitations on superplasticity. Theeffects are analyzed in essence, based on thermodynamic principle. In addition,the effects of cavitation's nucleation and growth on strain rate sensitivity (mvalue) are expessed quantitatively. |

| Keywords: | superplasticity cavitation nucleation growth strain rate sensitivity (m value) |
