Conclusions

  1. 1.

    During hot deformation by elongation the polymorphous α→γ transformation occurs in martensitic-ferritic steels under the influence of shear stresses, which increases the amount of austenite and lowers the amount of ferrite as compared with the equilibrium condition before deformation.

     
  2. 2.

    An increase of the deformation rate leads to more intensive development of the α→γ transformation in the process of deformation.

     
  3. 3.

    The effect of deformation by uniaxial tension on the α→γ transformation is qualitatively the same as deformation by torsion.
