摘要： The invention comprises a method and apparatus for equal channel angular extrusion (ECAE) of flat billets to control material structure and properties. The improvements of the method include the special systems of billet orientations, billet lubrication, billet ejection from dies, and a press/die control system those eliminate surface cracks, flashes and billet reshaping or deburring between passes. Therefore, multi-pass ECAE becomes a cost-effective industrial operation and may be applied to large 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.

摘要： Unique methods and apparatus are provided for deformation processing of advanced materials using this invention. Enhanced physico-mechanical properties are obtained by extrusion through a die assembly with two channels having equal cross sectional areas under near frictionless conditions. Also, large work pieces of advanced material can be intensively deformed by simple shear forces in a selected manner to produce the specific desired material characteristics. The results of applying the process to the working of cast metals, structure refinement and ductilization of brittle materials, structure-and texture-formation of the special alloys, and compacting of powder briquettes produces enhanced material characteristics in the finished product.
