METHOD FOR PRODUCING COMPOSITE ALUMINIUM-MATRIX MATERIALS CONTAINING TITANIUM CARBIDE BY SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS Russian patent published in 2023 - IPC B22F3/23 C22C32/00 B82Y30/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to methods for producing composite materials based on aluminium or its alloys using self-propagating high-temperature synthesis (SHS). The method for obtaining a composite aluminium matrix material containing titanium carbide by the method of self-propagating high-temperature synthesis includes the preparation of a powder mixture, its compaction and initiation of synthesis. When preparing a powder mixture, a reaction mixture is first prepared by mixing a titanium-containing material in the form of titanium or ferrotitanium powders with a titanium content of at least 60% and a carbon-containing material in the form of graphite, soot, carbon, fullerenes, nanotubes, graphenes or siliconized graphite, then the prepared reaction mixture is mixed with aluminium or aluminium alloy powder, taken in relation to the mass of aluminium or aluminium alloy to the mass of the reaction mixture from 1 to 100, while the ratio of the mass of titanium-containing material to the mass of carbon-containing material in the preparation of the reaction mixture is from 2 to 8. Powder of copper, nickel or their alloys or powder of chromium, vanadium or ferroalloys based on them can also be added to the reaction mixture in an amount of at least 3% by weight of titanium-containing and carbon-containing materials in the reaction mixture.

EFFECT: resulting materials are characterized by high physical and mechanical characteristics and can be remelted.
