Abstract
Based on the general solution to stress equilibrium differential equat ion and the analytical expressions in mechanical field of superplastic extrusion through cone-shaped die[1], in this paper the theoretical f ormulae haw been established for the technological processing specific ations of non-steady and steady extrusions through cone-shaped die. Ex perimental results on the typical superplastic alloy Zn-5wt/Al are in good agreement with the theoretical calculations.
