    摘要: A method of treating molten carbon-containing iron to produce a cast iron with a compacted graphite structure comprising adding to the molten iron in a single step a quantity of an alloy containing silicon, magnesium, titanium, calcium and a rare earth, the balance being iron. Preferably, the alloy has the following nominal composition by weight:30 to 80% Silicon,2 to 15% Magnesium,3 to 25% Titanium,2 to 10% Calcium,0.05 to 1.0% Cerium andThe Balance Iron.
