Thermomechanical treatment of steel in the process of isothermal transformation of supercooled austenite

  • 14 Accesses

Conclusions

  1. 1.

    Plastic deformation by stretching accelerates and ensures the more complete intermediate transformation of austenite.

  2. 2.

    The strengthening treatment, consisting of deformation of supercooled austenite in the initial stage of the intermediate transformation with subsequent completion of the transformation at the same temperature, makes it possible to increase the strength without a corresponding increase in hardness.

  3. 3.

    This strengthening treatment is most effective in the temperature range of the intermediate transformation.
