- This unique study, funded by the EPSRC and a Royal Society Industry Fellowship, reports on the dynamic interactions between ultrasonic bubbles/acoustic flow and the solidifying phases in metal solidification processes using synchrotron X-ray imaging at over 270,000 fps. It provides unambiguous experimental evidence and a robust theoretical interpretation of the dominant mechanisms of solidification under ultrasound, which have been debated for over 60 years. It safeguards the UK’s world leading position in this important research area, and helped secure £1.9M of further EPSRC collaborative grants (EP/R031819/1, EP/R031975/1, EP/R031665/1, EP/R031401/1) to investigate ultrasonic processing of 2D materials.
