Conclusions

  1. 1.

    Thermomechanical treatment can, depending on its type and on the steel's structure, either stabilize or destabilize the residual austenite with respect to martensite transformation during the cooling and subsequent deformation processes. The effects of TMT on the γres →α transformation during cooling and during deformation can be either the same or the opposite.

  2. 2.

    The mechanical properties of two-phase Cr−Mn steels after TMT are determined by the martensite/austenite ratio in the structure, as well as by the development of the γres →α transformation during deformation.

  3. 3.

    By adjusting the structure, the phase strengthening, and the residual austenite stability through a correct selection of TMT type, it is possible to produce high mechanical properties in the Cr−Mn steels studied.
