FIELD: electrical engineering and metallurgy, particular, methods of treatment of liquid metals and alloys; foundry, metallurgy. SUBSTANCE: the offered method includes exposure of liquid metal stream to effect of periodic pulses of magnetic field directed along the axis of stream. In this case, duration of magnetic field pulses decreases in direction of metal flow. EFFECT: increased mechanical properties by ecologically clean methods. 3 dwg, 1 tbl
