Bubble dynamics in melts of the light-melting metals by ultrasonic forces

The oscillation of air and argon bubbles were investigated in dependence on ultrasonic pressure 1-12 atm for ambient radius 1-10 microns. The results of digital calculation of the Rayleigh - Plesset equation, Flynn`s equation and Gilmore’s equation, the thresholds of cavitation, the criterion of bubble collapce in melts of the light-melting metals and water were presented.
