Abstract

Factors causing the solid-phase dispersal of particles of alloying elements in the aluminum melt depending on their nature are considered. It is shown that the particles can be fragmented under the effect of uniform tensile stresses appearing due to the particles heating. The reasonability of using additional external effects (for example, magnetic-pulsed treatment of the foundry-alloy melt) to intensify the assimilation of silicon in liquid aluminum and provide the microcrystalline structure of the foundry alloy is substantiated theoretically and confirmed experimentally by the example of the Al–20 wt % Si foundry alloy.
