Formation of the structure and properties of a high speed steel tool by severe plastic deformation and subsequent heat treatment


Presents the conditions of formation of structure in the high-speed tool steel Р6M5 (Russian standard) using severe plastic deformation (SPD). Integrated processing workpieces included draft initial billets subsequent by high-pressuretorque (HPT) (HPT) at room temperature and heat treatment. The influence of treatment parameters SPD on the structural features of deformed blanks and carbide homogeneity. It is shown that the rational parameters of processing allow to obtain high performance tool steel P6M5.
