摘要

Ultrasonic surface rolling (USR) technology combines with the characteristics of high-energy impact and static load rolling. The USR-processed workpiece has the advantages of high surface finish, deep deformation layer,large compressive residual stress and obvious grain refinement. It can greatly improve the fatigue strength of metal materials through appropriately adjusting process parameters, thus it has been widely used in manufacturing industry. Since the invention of USR. a large number of studies on processing technologies and mechanisms have been conducted. It is also extensively applied to important metal materials and key parts. So far,the research on the effect of USR process parameters on the surface integrity and fatigue properties is relatively scattered and lacks systematic summary. Firstly,this paper briefly introduces the working principle and controllability of USR. Then, the residual stress and microstructure induced by different USR parameters, and the relaxation of residual stress during fatigue loading are summarized. The effects of surface integrity induced by USR with different parameters on fatigue properties as well as the potential mechanisms are criticized. The combined strengthening methods related to USR are described, and the application prospect of USR metal materials is forecasted.
