Abstract

Abstract

In order to improve the fatigue life and surface pressure stress of 50^# steel axle, its stress change rules were analysed, its residual stress was measured by X ray method when the axle surface was going through the process of low-temperature quenching and the various process of rolling and pressing.Measured results show that the residual stress of 50^# steel axle surface are improved greatly, the maximum improved value is 556 MPa, which shows that the method can efficiently improved the axle fatigue life cycle.
