Apparatus and method for deformation processing of metals, ceramics, plastics and other materials
MetadataShow full item record
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.
