Effect of Initial Structural State on Formation of Structure and Mechanical Properties of Steels Under ECAP

  • I. E. Volokitina
  • G. G. Kurapov

The effect of preliminary heat treatment and equal-channel angular pressing (ECAP) in a stage die on the microstructure and mechanical properties of steels 45 and 35KhM is studied. The grain size, the microhardness, and the strength and ductility characteristics of the steels after the ECAP are determined. The suggested modes of thermomechanical treatment improve the combination of the properties of the steels studied.
