| Abstract: | The characteristics of fatigue fracture and crack propagation course on spring flat of steel 55SiMnVB have been studied. The results show that the fatigue resistance of steel is improved by the flat surface residual stress produced through shot peening which has crack closure effect to reduce the velocity of crack extension. |
