Fatigue improvement and residual stress relaxation of shot-peened alloy steel DIN 34CrNiMo6 under axial loading

•Shot-peening process, compared with machined specimens, increases by 21.8% fatigue limit.•Quasi-static tests show more stress relaxation with compressive loads.•High stress magnitudes produce relaxation along the complete fatigue life.•Surface stresses relaxation model for SP is obtained.•FWHM is a...
