| Abstract: | The dynamics of grain growth is studied in detail for the superplastie deformation of precipitation-hardened alloys, thus deriving an expression of grain growth in superplastie deformation and discussing the effect of grain growth on sueperplasticity.The grain growth is concluded that it will decrease the strain rate sensitivity or m value. The physical meaning of the effect of grain growth is discussed and expressed quantitatively. |

| Keywords: | superplastic deformation grain growth strain rate sensitivity (m value) |
