This research work is done to investigate the possibilities how to mix and disperse ceramic nanoparticles in liquid metals and keep them dispersed during solidification. We investigate contactless electromagnetic methods to produce metal matrix nano-composites. Dispersed particles improves mechanical and thermal properties of the metals by refining metallic grains and limiting crack propagation. We use intensive electromagnetic interaction from capacitor bank discharge to create pressure oscillations liquid metal which induces acoustic cavitation which then causes intensive micro-scale jet which is able to break particle agglomerates.
