FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy, in particular to method of Al alloys affinage and modification. Method includes metal melting, melt treatment by nanosecond electromagneticpulses (NSEMP) for 15 minutes, and pouring in moulds, at that prior to treatment using NSEMP the melt is treated by the affinage salts, and during treatment or after NSEMP treatment the melt is subjected to evacuation for 15 minutes.EFFECT: increased quality of Al alloy castings due to gas porous exclusion.4 dwg |
