METHOD FOR PRODUCING ALLOY CARBIDE STEEL Russian patent published in 2007 - IPC B22F3/23 C22C33/02 C21B15/02 

FIELD: powder metallurgy, namely production of carbide steels.

SUBSTANCE: method comprises steps of mixing charge containing termite mixture including 78 - 82 mass % of iron scale powder and 18 - 22 mass % of aluminum powder; at mixing adding alloy cast iron in quantity consisting of 24 - 26 mass % of termite mixture and titanium carbide in quantity consisting 18 - 20 mass % of termite mixture. Melting is realized by means of self-propagation high-temperature synthesis under layer of acidic flux with thickness 8 - 10 mm.

EFFECT: high hardness and uniform structure of carbide steel.
