METHOD OF PRODUCING COMPOSITE METAL ALLOY CONTAINING TITANIUM CARBIDE Russian patent published in 2020 - IPC C22C1/02 C22C32/00 B22F3/23 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to metallurgy, namely to methods of alloying, production of composite alloys, and can be used for production of cast materials additionally alloyed with titanium carbide. Method of producing composite alloy containing titanium carbide includes introduction of molten copper, nickel, cobalt, iron or alloys based thereon exothermic reaction mixture with subsequent formation of ingot. Exothermic reaction mixture consists of mixture of powdered titanium-containing component in form of titanium or ferrotitanium with titanium content of not less than 60 % and carbon-containing component in form of soot, graphite, siliconized graphite or boron carbide, wherein weight ratio of titanium to carbon weight in exothermic reaction mix ranges from 2 to 8, while amount of introduced exothermic reaction mix does not exceed 30 % of melt weight. Amount of said additives does not exceed 50 % of the weight of the mixture of titanium and carbon-containing components. Enabling possibility of titanium carbide doping of high-temperature melts.

EFFECT: excess of one of the components of the exothermic reaction mixture compared to the stoichiometric composition provides additional formation of strengthening phases in the melt.
