Purpose of the research is to determine physical conditions of modification and technological parameters of electrohydropulse treatment (EHPT) and pulse electric current treatment (PECT) of the melt, thus providing an efficient action of modifying elements, structure and mechanical properties of hypereutectic silumins. Technological bases of complex treatment of piston hypereutectic silumins by electrohydropulse and electric current action on the melt in the above-liquidus zone together with chemical modification processes. Physical and chemical activity of modifying additives increases under an action of pulse stressing of a melt, thus increasing its crystallization ability. The reduction of Si1 crystal sizes thus decrease to 20 µm, SiЭ - to 10 µm, which provides increasing the ultimate strength by 24% and elongation from 0.8 to 3%.
