Conclusions

  1. 1.

    Tempering of quenched steel 40KhNMA under stress increases its resistance to small plastic deformations and the fatigue strength in tests for more than 106 cycles.

     
  2. 2.

    The effect of tempering under stress on the fatigue strength is evidently due to the longer period required for development of the fatigue crack.

     
  3. 3.

    Tempering under stress can be used as a strengthening treatment for machine parts.
