ABSTRACT:
A shear-extrusion method of severe plastic deformation for fabrication of metal shapes with ultra-fine structures is described. The improvements of the method include unidirectional shear of any required intensity during one step processing and under high hydrostatic pressures, fabrication of long products with different cross-sections, refinement of low ductile alloys, the increase of productivity and cost reduction. The method can be realized as forward extrusion, backward extrusion, semi continuous extrusion and extrusion of hollow shapes in portal dies with a welding chamber.
