Abstract：A new developed surface mechanical enhancement technique,Ultrasonic Deep Rolling(UDR),was introduced.UDR was used to treat TC4 titanium alloy specimens.Residual stress and work hardening distribution,surface profile and surface roughness of the specimen were analyzed.Results show that a deep layer of high value compressive residual stress with moderate work hardening was developed.Surface roughness was reduced substantially.Advantages and potential applications of the UDR technique were discussed.
