Relaxation behavior of laser-peening residual stress under tensile loading investigated by X-ray and neutron diffraction

Compressive residual stresses induced by peening techniques improve the strength properties of steels, such as fatigue and stress corrosion cracking. However, the compressive residual stress might be reduced owing to thermal and mechanical loading in-service. In this study, the behavior of surface a...
