FIELD: metallurgy.
SUBSTANCE: method involves addition to the molten metal of the modifying agent containing ultrafine high-melting particles of titanium carbonitride and titanium, chrome, molybdenum, tungsten, niobium, aluminium, nickel and manganese particles. Modifying agent is added to the molten metal heated to 1480-1600°C in the form of a briquette with density of 1.05-1.2 of molten metal density and porosity of 1.0-5.0 vol %.
EFFECT: invention allows adding the modifying agent to molten metal without any considerable changes of the design of melting-pouring equipment; provides the uniform distribution of high-melting particles for molten metal volume and prevents the dilution, coagulation and floating of high-melting particles, which allows obtaining the alloy with high strength characteristics and fine homogeneous structure.
