Abstract

Products made from wire and bars with uprated physical and mechanical characteristics are widely used in mechanical engineering. Such characteristics cannot be achieved by classical thermal and mechanical techniques. The use of new materials motivates development of new methods of hardening and achieving the required mechanical properties. Bulk nanomaterials, including those resulting from severe plastic deformation, whose mechanical properties are predetermined by ultrafine-grained structure, combine high strength, good ductility, and other properties. The purpose of severe plastic deformation is to accumulate plastic strain in the workpiece. This requires certain conditions, such as nonmonotonicity of deformation.
