Conclusions

  1. 1.

    A periodicity in the changes in the strength of austenite was observed in steel 03Kh12N7YuM in relation to the number ofγ⇄α cycles—the strength increases with increasing numbers of cycles but drops periodically.

  2. 2.

    The periodic drop of the strength of austenite during thermal cycling is due to recrystallization of phase strain hardened austenite after a certain number ofα⇄γ transformations. The periodic change in the strength of the steel is also accompanied by a periodic change in the amount of retained austenite.

  3. 3.

    The change in the strength of austenite under the influence of thermal cycling has almost no effect on the strength of martensite formed from it during the following γ → α transformation.
