| Abstract: | Calculation formulae of superplastic extrusion are derived through the Sach's method in plastic analysis and Backofen's constitutive equation of superplasticity. Calculating formula and modle of Tang S are improved insuperplastic extrusion.Calculus of the theory are experimentlly studied through superplastic with Zn-22Al. |
