Conclusions

  1. 1.

    The sensitivity of ShKh15 steel with different hardnesses to stress concentrations depends to a great extent on the method of preparing the stress concentrator.

    If the stress concentrators are made before heat treatment the sensitivity to stress concentrations is high and reaches values considerably higher than unity, apparently due to the presence of residual tensile stresses in the stress concentrators. The value of Keff increases monotonically with increasing hardness.

    When the stress concentrators are made after heat treatment the sensitivity to stress concentrations is much lower and the value of Keff has a maximum at a hardness of HRC 30–40. This result is in good agreement with the results obtained in [3] for 30KhGSA steel.

  2. 2.

    It was shown that the dependence of plastic deformation occurring during one cycle under stresses equal to the fatigue limit on the hardness corresponds (at high hardnesses) to the results obtained with samples in which the stress concentrators were made by the second method.

We also found a correlation between the sensitivity to stress concentrations and the value of σb/σp within the whole range of hardnesses investigated.
