Аннотация

The results of an experimental study of acoustic emission spectra (AE) in the frequency range of 20–200 kHz, which occur when the temperature of the aluminum melt decreases from 860 to 660°C. The paper discusses the relationship between acoustic signals and the processes of structural transformations in the melt as the temperature.
