Summary plot of a series of numerical calculations for the threshold amplitude \(P_{A}^{{rth}}\) of acoustic pressure as a function of an ultrasound frequency \(\nu\). The initial bubble radius is \({R_0}={10^{ - 5}}\) m. The orange and blue curves correspond to the 316 L and Ti-6Al-4 V melts. The calculated values are connected by straight segments for ease of perception. The black diamond point marks the resonant conditions for 316 L.
