Corrugation and pitting of rolling surfaces — are they contingent upon ultrasonics ?
Wear, 1975This article is an abridged version of essay number 28/1973 held in the Archiv fur Eisenbahntechnik. Rail corrugations which were a familiar phenomenon in the 1890's and similar periodic forms of wear occur in other rolling-contact combinations. In the following discussion an attempt is made to explain these manifestations.

Control of ultrasonic surface rolling process machine tool for aero-engine blades
2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018The surface quality of blades affects the performance and security of aircraft engines. Ultrasonic surface rolling process (USRP) can be used to improve service life of alloys. However, blades with complex design specifications are difficult to processing, especially the thin-walled leading/trailing edge should bear the loads during the process of ...

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 ...
