ABSTRACT:
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.
