摘要： 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.

摘要： Method and apparatus for fabrication of large thin parts, such as panels having integral stiffeners arranged in any desired pattern, for superplastic and semisolid forming of complicated components, and for consolidation and bonding of powder and composite materials into flat products, include forging-rolling between a flat die and a circular die with a ratio of a contact length between the circular die and a billet to a billet thickness between 20-75 that prevents a material flow in a rolling direction and extrudes the material into die cavities. The circular die is formed as a ring-shaped element sliding along cylindrical guide surface. Both dies are displaced by press to squeeze and forge a billet into a product. For semicontinuous processing of very long parts, the dies are divided into a plurality of sectioned elements which are periodically introduced into a working zone.
