Ultrasonic cavitation processing (USP) has gained a lot of momentum the last decade as an effective, environmentally friendly, and economical process. The basic principle of USP is conversion of acoustic energy into mechanical-impact energy by means of cavitation bubbles implosion and kinetic energy via acoustic streaming. However, a broad application of this technology is hindered by the lack of understanding on the fundamental mechanisms governing USP. To this end, an extensive research program to elucidate and unveil the governing mechanisms behind USP that are necessary for process optimisation and scale up has been undertaken. In this talk, recent results on the work to understand and control USP for applications related to ultrasonic melt treatment and ultrasonic exfoliation of nanomaterials for the production of high performance aluminium alloys and the development of high quality and large in size Graphene flakes will be set out.
