Abstract
The results of an experimental study of the acoustic emission spectra in the frequency range 20-200 kHz, which occur when the temperature of the aluminum melt decreases from 860 to 660 °C are presented. The interrelation of acoustic signals with the processes of structural transformations in the melt with a change in temperature is considered.
