“… depends on the frequency, namely, as the sound frequency increases, the absorption coefficient decreases. However, in a reference [16], in contrast to the reference [15], no frequency dependence was observed. The sound absorption value in liquid sulfur is proportional to the frequency square, i.e.…”

The temperature dependences of ultrasound absorption and propagation speed in simple semimetals, semiconductors, and semiconductor compounds have been studied in this article. Experimental and theoretical results testify to the microheterogeneity of semimetals and semiconductor melts. Generalization and analysis of experimental data on the absorption and propagation speed of ultrasound in melts based on D.I. Mendeleev periodic law clearly indicate the presence of micro-groups of atoms (clusters) in them, microheterogenizing melts of semimetals and semiconductors. The urgency of this problem is predetermined by the problem of the liquid state of matter. The dependence of ultrasound absorption and propagation speed on temperature is measured using several groups of samples in paper, each group is heated to a different temperature. It is proved that melts have clustered in their atomic matrix, and so melts with semiconductor properties are micro-inhomogeneous. These results are needed to scale melt sonication to an industrial scale and are needed to provide valuable new insights into temperature dependencies of ultrasound absorption.

The presented results are based on experimental and computational studies aimed at justifying the application of the cavitation-acoustic hypothesis in describing the process of “fine” fragmentation of hot droplets falling into cold water. Such a process plays a crucial role in small-scale steam explosions. Brief descriptions of other possible mechanisms for the fragmentation of liquid-metal droplets under different conditions are provided, with the main focus given to the fragmentation process induced by shock waves generated by pulsed laser irradiation and mechanical impact. Experimental data on pressure impulses resulting from the collapse of vapor bubbles formed upon contact between the coolant (cold water) and the overheated surface are presented. It is demonstrated that the obtained data, along with photographic evidence of the molten fragments, are consistent with the assumption of the development of the fine fragmentation process according to the cavitation-acoustic scenario. Approximate calculations conducted within the acoustic approximation support this hypothesis.

The article examines the process of crystallization of Wood alloy using the ultrasonic method. The dependence of the determination of the speed of sound in three aggregate states of the alloy (liquid, solid, transition (liquid-solid)) was derived. The relation-ship with the amplitude values of the sound signal, a single pulse in determining the speed of sound, as well as in determining the state of the alloy is carried out. The data obtained allow us to analyze the state of the alloy and the measurement time and the specified frequency range directly in the process of crystallization.
