Residual stress of as-deposited and rolled Wire + Arc Additive Manufacturing Ti–6Al–4V components [PDF]
, 2016 Wire + arc additive manufacturing components contain significant residual stresses, which manifest in distortion. High-pressure rolling was applied to each layer of a linear Ti–6Al–4V wire + arc additive manufacturing component in between deposition ...

Active and passive compliant force control of ultrasonic surface rolling process on a curved surface
Chinese Journal of Aeronautics, 2022 Abstract Ultrasonic surface rolling process (USRP) is one of the effective mechanical surface enhancement techniques. During the USRP, unstable static force will easily do harm to the surface quality. In order to achieve a higher surface quality on the part with a curved surface, an active and passive compliant USRP system has been developed.

Ultrasonic roll bite measurements in cold rolling: Contact length and strip thickness [PDF]
, 2017 In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity.
