Conclusions

  1. 1.

    36Kh9N7M4GS2 steel strengthened by warm deformation possesses high resistance to low-cycle fatigue.

     
  2. 2.

    The high resistance of this steel to fatigue failure is caused by the presence of an austenitic texture occurring as a result, of warm deformation and the formation of deformation martensite in cyclic loading.
