Abstract

The influence of aerothermoacoustic treatment on the formation of the microstructure and the mechanical properties of cast aluminum alloys (silumins) is considered. The experimental data demonstrate that this treatment, which is included in the technological cycle of standard heat treatment or partly replacing it, increases the strength of the alloys by 35–40% at a retained or slightly decreased plasticity.
