摘要：
By means of an optimization method a set of material parameter included in a superplastic constitutive model developed by Jin is identified in this paper, The superplastic constitutive model considers three types of microscopic deformation mechanism and the grain grow process. In addition, the constitutive Model has been partly improved. The DFP optimization method is adopted in the parameter identification, Finally, some calculated examples for Ti-6Al-4V alloy and 7475Al alloy are shown, The calculated curves are in agreement with the experimental ones very well.
