Abstract：

In order to enhance the comprehensive performance of T2A steel wheel surface, the surface was treated by the ultrasonic rolling reinforcement technology, and the influences of ultrasonic rolling force on surface structure, hardness and residual stress of T2A steel wheel were analyzed by experiment. The results show that the grains on the surface of sample have an obvious deformation, and the deformation layer thickness increases significantly with the increasing of ultrasonic rolling force. The microstructure near the surface produces strong plastic deformation, and as the ultrasonic rolling force increases to 300 and 400 N, the steel surface forms finer nanocrystals and produces some amorphous structures. The plastic deformation of steel causes work hardening on the surface. In addition, the grain refinement increases the hardness of surface. As the ultrasonic rolling force continues to increase to 400 and 500 N, the hardnesses of 100 μm from the surface are 352 and 358 HV respectively. The distribution of the maximum residual compressive stress on the surface of T2A steel shows a rising trend with the increasing of ultrasonic rolling force. When the ultrasonic rolling force increases, the effect depth of residual stress in the sample matrix also increases significantly, and the increase of ultrasonic rolling force also expands the effect depth of residual compressive stress.
