STRUCTURAL AND PHASE COMPOSITION OF STEELS R6M5 AND 40H AFTER JOINT HEAT TREATMENT

Abstract

The paper discusses special features of heat treatment of axial (end) cutting tool bimetallic billets made using the resource-saving technology with the aid of simultaneous hot plastic deforming through a forming die. The microstructure and hardness of 40X and P6M5 steels have been investigated after subjecting them to various conditions of heat treatment.
