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.
Abstract: A front end module including a plastic component connected to a metallic substrate. The metallic substrate can be formed by hydroforming and shaped into a substantially unitary member. The plastic component is then molded about the metallic substrate and simultaneously forms connections thereto at discrete locations along the length of the metallic substrate.
