FIELD: metallurgy; may be used in improvement of properties of grey iron castings. SUBSTANCE: method includes thermocycling with heating to temperature exceeding the liquidus temperature by 30-200 C and subsequent cooling in the air. EFFECT: reduced volume fraction of graphite segregations, their size reduction and more uniform distribution in casting cross-section. 2 cl, 1 tbl
