Effect of ultrasonic surface rolling on microstructure and rolling contact fatigue behavior of 17Cr2Ni2MoVNb steel

Surface and Coatings Technology, 2019
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.

Cavitation effect in two-dimensional ultrasonic rolling process

Ultrasonics, 2021
The ultrasonic cavitation effect can improve the machining quality. In order to study the formation process of cavitation in two-dimensional ultrasonic rolling process (TDUR) and its influence on processing, a simulation and experimental study of cavitation in TDUR was conducted to further improve the processing quality. The pressure distribution model

Ultrasonic evaluation of double poured rolls

NDT & E International, 2000
Ultrasonic evaluation of the bonding characteristics in an infinitely chilled double poured rolls is carried out. During manufacturing process there are defects in the form of small holes or inclusions in these rolls. These defects act as points of stress in addition to the service stresses. By grinding, stress redistribution occurs.

Effect of ultrasonic peening technology on the thermal fatigue of rolling mill rolls

The International Journal of Advanced Manufacturing Technology, 2017
In this study, the use of ultrasonic peening technology (UPT) on the rolling mill roll graphite steel GSH48 was surveyed in order to improve some surface mechanical and thermal properties. UPT is one of the newest technologies of severe plastic deformation in which vibratory tool strikes the workpiece surface with continual reciprocating motions ...
