Abstract Ultrasonic surface rolling (USR) treatment with different rolling loads (600, 800, 1000 and 1200 N) was introduced to the 17Cr2Ni2MoVNb steel. The microstructure and rolling contact fatigue (RCF) behavior after USR treatment were investigated.

Finite element modeling of ultrasonic surface rolling process
Journal of Materials Processing Technology, 2011Abstract Ultrasonic surface rolling (USRP) is a newly developed process in which ultrasonic vibration and static force are applied on work-piece surface through the USRP operator to generate a nanostructured surface layer with mechanical behaviors highly improved.

Investigations on the nanocrystallization of 40Cr using ultrasonic surface rolling processing
Applied Surface Science, 2008Abstract Ultrasonic surface rolling processing (USRP) was applied on quenched and tempered 40Cr. Microstructure observations of USRP specimen surface indicate that the processing can both get nano-structured layers, with grain size of 3–7 nm, and reduce the surface roughness to 0.05 μm.

Effect of Surface Ultrasonic Rolling on Evolution of Surface Microstructure of EA4T Axle Steel
Journal of Materials Engineering and Performance, 2021The effect of surface ultrasonic rolling (SUR) on the evolution of surface microstructure of EA4T axle steel is studied by using several microanalysis techniques. Fatigue life of samples after SUR is measured by means of rotary bending fatigue test. After SUR, the surface roughness of the sample is reduced, and the grain size in surface microstructure ...

Investigation on Dynamics of Ultrasonic Surface Rolling Process
Advanced Materials Research, 2013Ultrasonic surface rolling processing (USRP) is a surface nanocrystallization method developed recently, which can bring metal surface with superior properties. In order to obtain the motion state of the processing tip during USRP, a 3D dynamic finite element model was adopted to simulate the response of processing tip.
