Influence of Original Surface Roughness on Ultrasonic Deep Rolling Effects
Advanced Materials Research, 2014A series of samples which have different surface roughness made by 45 steel were treated by Ultrasonic Deep Rolling (UDR), influence of original surface roughness on UDR effects, such as surface profile, surface roughness and residual stress, were studied. Results shows that surface roughness was reduced substantially through UDR treating and lager the

Ultrasonic Measurement of Anisotropy in Rolled Materials Using Surface Wave
Japanese Journal of Applied Physics, 1986An ultrasonic technique for measuring the velocity of surface wave is proposed, and is applied to determine the velocity as a function of propagating direction in aluminum 5052, 5083 and 6061, and steel SM41A. From these data, each slowness diagram in the specimens was determined and it was found that this diagram can be approximated to a ellipse ...

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.
