METHOD FOR PRODUCING ALLOY FROM IRON-CONTAINING PRODUCTION PROCESS REJECTED MATERIALS Russian patent published in 2007 - IPC B22F3/23 C22C33/02 C21B15/02 

FIELD: powder metallurgy, namely production of alloys from iron-containing rejected materials of manufacturing process.

SUBSTANCE: method comprises steps of mixing charge containing thermit including 78 - 82 mass % of iron scale powder and 18 - 22 mass % of aluminum powder; at mixing adding alloyed cast iron in quantity consisting 18 - 20% of thermit mass, titanium carbide in quantity consisting of 18 -20 % of thermit mass and titanium boride in quantity consisting of 4 - 6% of thermit mass; then melting charge due to realizing self-propagating high-temperature synthesis.

EFFECT: possibility for producing predetermined composition alloy of high rigidity, ductility and heat resistance.
