摘要：

The deformation zone is bounded by two spherical surfaces of velocity discontinuities, having radius R//1 and R//2 with their centers at a. R//1 and a. R//2 from the apex of a conical die. The coefficient a varies depending on the process variables including the friction factor. The flow in the deformation zone is directed along radial lines toward the apex of the cone. For extrusion through large angle dies, redundant shear in the outer surface of the indirectly extruded bar exceeds that of the directly extruded one.
