Study of the effect of surface strain-hardening on fatigue crack growth in steel 30KhGSN2A

  • Scientific-Technical Section
  • Published:
Strength of Materials Aims and scope

Conclusions

  1. 1.

    Strain-hardening the surface of steel 30KhGSN2A is an effective means of slowing fatigue cracks during their initial growth; the growth rate can be reduced by a factor of 4–10, depending on the methods and conditions of surface strain-hardening.

  2. 2.

    The number of cycles corresponding to the crack-growth state in cylindrical specimens and parts with strain-hardened surfaces subjected to bending can be evaluated with sufficient accuracy from Eq. (13).
