摘　　要：Ⅰ. INTRODUCTIONBecause of the strong structural sensitivity of superplastic deformation, the m-value, which is an important index for the evaluation of superplasticity of materials, is related not only to stress state, but also to pressuring method. In the superplastic bulging re.value formula measured by means of fixed height jump-pressure established by the author,
