Abstract
Methods and apparatus are described for the plastic deformation of flat rectangular billets. Simultaneous extrusion of two flat rectangular billets through a die having channels of equal cross-sectional area alters billet material structure, texture, and physicomechanical properties without altering billet dimensions. The extrusion system of the present invention prolongs die lifetime, increases punch stability, decreases punch working load and pressure requirements, eliminates the difficulties associated with lubricating movable parts of the die under high pressure and temperature, optimizes use of press space, and provides for automatic and independent ejection of extruded billets from the die. The methods of plastic deformation processing of flat rectangular billets in the present invention allow for the production of a variety of structural, textural, and physicomechanical properties previously unobtainable for large flat rectangular billets.
