Popis:	An assessment of the grain refining effect of nanosecond electromagnetic pulses on the structure of cast aluminum alloys of the Al-Mg-Si system is carried out. The relationship between the amplitude of nanosecond electromagnetic pulses (5, 10, 15 kV) and the structural and morphological parameters of the irradiated aluminum alloys is shown. It was found that the processing of the melts at an amplitude of 15 kV is accompanied by the greatest refinement of the structural components of the alloy, and also by a change in their morphology and a decrease in microporosity in the structure of cast ingot. Theoretical analysis of the influence of nanosecond electromagnetic pulses on the structure and properties of aluminum alloys from the standpoint of the theory of the microheterogeneous structure of metal melts is given.
