TL;DR: In this paper, the authors describe the increasing demands in their applications to improve product efficiency, cost-effectiveness and the development of superior specific properties of composite materials/structures.

TL;DR: In this article, the authors acknowledge financial support from the UK Engineering and Physical Science Research Council (EPSRC) for the Ultra-Cast project (grants EP/L019884/1;EP/L019825/1, EP/l019965/1), and also acknowledge the financial support by the Royal Society Industry Fellowship awarded in 2012-2016.

TL;DR: In this article, the dynamic behavior of ultrasound-induced cavitation bubbles and their effect on the fragmentation of dendritic grains of a solidifying succinonitrile 1 wt pct camphor organic transparent alloy have been studied experimentally using high-speed digital imaging and complementary numerical analysis of sound wave propagation, cavitation dynamics, and the velocity field in the vicinity of an imploding cavitation bubble.

TL;DR: An extensive research programme into fundamental mechanisms of cavitation melt processing using state-of-the-art and unique facilities and methodologies is undertaken, providing valuable new insights and knowledge that are essential for upscaling ultrasonic melt processing to industrial level.

TL;DR: In this paper, the dynamic interactions between the ultrasonic bubbles/acoustic flow and the solidifying phases in a Bi-8% Zn alloy were investigated using the ultrafast synchrotron X-ray imaging (up to 271,554 frame per second).
