The sound field, acoustic streaming and cavitation of the magnesium alloy melt during ultrasonic melt treatment were investigated using numerical simulation method. The simulation results show that a radial sound field forms under the ultrasonic probe. The ultrasonic cavitation in the melt with a single-bubbly-change model under different sound pressures was calculated by solving the Rayleigh- Plesset equation. The relationship between sound pressure amplitude and the ultrasonic cavitation in the melt is also discovered. The sound fields of the melt with different immersed depths of the ultrasonic probe are calculated. The results show the optimal immersed depth is about 30 mm for the same crucible size used in the present study. Furthermore, the corresponding optimal immersed depth can be calculated for different crucible sizes or different melts by the present numerical method, which is important for the practical ultrasonic processing.
