| Abstract: | The mode of residual stress field produced by rolling, the quantitative relationship between maximum residual compressive stress and its influence depth and the final residual stress field after relaxation were established on the basis of tests. The influence of final residual stress field on fatigue life was analysed by using stress field intensity method sulfgested by authors. |

| Keywords: | rolling fatigue residual stress relax. |
