Simultaneously improved strength and ductility of selective electron beam melted Ti6Al4V using ultrasonic surface rolling process

Journal of Materials Research and Technology
In this study, surface ultrasonic rolling processing (USRP) was used to strengthen the surface of Ti6Al4V via selective electron beam melting (SEBM), and the effect of different loads (200 N, 400 N, 600 N, 800 N, 1000 N) during USRP on the microstructure

A new approach for the measurement of film thickness in liquid face seals [PDF]

Face seals operate by allowing a small volume of the sealed fluid to escape and form a thin film between the contacting parts. The thickness of this film must be optimized to ensure that the faces are separated, yet the leakage is minimized. In this work

Modelling of multiple impacts for the prediction of distortions and residual stresses induced by ultrasonic shot peening (USP) [PDF]

, 2012
During a manufacturing process, the ultrasonic shot peening (USP) technique can be used as the final surface treatment. The aim of this operation is to introduce surface compressive residual stresses in order to prevent crack propagation advancement ...
