Abstract
The complete solution of stress and strain were obtained for commercially pure aluminum and superplastic alloy of the eutectic of Pb-Sn in an axisymmetric extrusion process of extrusion ratio 4 and a half cone angle of 45°. The extrusion speed was 0.1/min for aluminum and.003 in/min for superplastic Pb-Sn. The stress components along and perpendicular to the flow lines were calculated for different values of workhardening and strain-rate exponents. The shear stress along the boundary was determined. The size of the tension zone was compared for different material properties.
