Abstract:
Shot peening is a sort of cold working, so peened surface of metal has been generally work-hardened. But prestrained metal surface shows work-nonhardening or work-softening
after shot peening. This phenomenon generally happens under combined cold deformation and the case of shot peening was already reported in the proceedings of 2nd ICSP for
compressive prestrained steel.
I
n this report, we described the result of fatigue test for
work-nonhardened and work-softened steel specimen which was prestrained by rolling under various reduction ratio before shot peening.
