Özet

Shot peening is a cold working process by which residual compressive stresses are induced in the surface and near-surface region to increase the fatigue strength and the resistance to stress corrosion cracking This study covers non-destructive evaluation of surface residual stresses in the shot peened steel components by the magnetic Barkhausen noise method For this purpose various sets of steel specimens were prepared by a controlled shot peening process with different intensities impact angles and coverage values The measurements showed that a clear relationship exists between surface residual stresses and the Barkhausen noise signals
