The fatigue fragmentation of dendritic structures of a SCN-5wt.% Camphor transparent alloy in an ultrasound field was investigated systematically using high-speed imaging. Dynamic interactions between oscillating ultrasonic bubbles and the primary an...

Ultrafast X-ray imaging and modelling of ultrasonic cavitations in liquid metal (2013)
Presentation / Conference Contribution
Lee, T. L., Khong, J. C., Fezzaa, K., & Mi, J. Ultrafast X-ray imaging and modelling of ultrasonic cavitations in liquid metal

The dynamics of ultrasonic bubbles in liquid metal are captured in-situ for the first time using the ultrafast X-ray phase contrast imaging facility housed at the Advanced Photon Source, Argonne National Laboratory, in the USA. The experimental obser... Read More about Ultrafast X-ray imaging and modelling of ultrasonic cavitations in liquid metal.
