Abstract
The invention relates to an iron alloy and a preparation method thereof. The iron alloy is prepared from the following raw materials by weight percent: 1-1.4% of carbon, 6-7% of manganese, 4-5% of copper, 1.5-2.5% of titanium, 0.01-0.03% of tellurium, 0.01-0.03% of bismuth, 0.03-0.05% of molybdenum, 0.01-0.03% of zirconium, 0.15-0.30% of tungsten, 0.5-1.2% of silicon, and the balance of iron and unavoidable impurities. The raw materials are put into a melting furnace so as to be heated to a liquid form and are mixed by stirring, nitrogen is introduced through the bottom of the melting furnace in a smelting state, and then cold rolling is carried out.
