Abstract—A method for obtaining cast composites using the effect of low frequencies on the melt is presented.
Some features of the process and the results of vibrational treatment are unobvious and require theoretical
explanation. The factors that prevent the introduction of the powders into the melt volume and the factors affect-
ing the variation in the sizes of the structural components of the melt during low-frequency melting are consid-
ered. A new interpretation of the crushing and coagulation mechanism during low-frequency treatment (LFT)
with a mathematical description and experimental confirmation is proposed.

Keywords: low-frequency melt processing, dispersing, coagulation, composite alloy, microstructure, conglom-
erate
