Abstract: This paper has used the engineering calculus slab method for the deformation derivation of the deformation forces during the backward extrusion of the superplastic state of the metal. The formula of the unit average pressure pave was obtained. The unit average pressure estimated was approximately equal to experimental value for Zn-22% A1 eutectoid alloy.

Key words: Analytic calculation, Performance evolution, Conceptual design
