METHOD OF PRODUCTION OF A TITANIUM-ALUMINIUM-VANADIUM ALLOY Russian patent published in 2021 - IPC C22B5/04 C22C14/00 C22F1/18 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to methods of production of a product or a part from a refined titanium-aluminium-vanadium alloy. The reagent mixture containing an ore mixture of titanium-containing ore and vanadium-containing ore, an aluminium reducing agent and a viscosity regulator is heated. Thermal extraction reaction is initiated in said reagent mixture forming a crude product from a titanium-aluminium-vanadium alloy. The viscosity regulator ensures effective separation of the titanium-aluminium-vanadium alloy crude product from the residual slag in two layers during the extraction reaction through correlation of reagents in the mixture. A titanium-aluminium-vanadium alloy crude product is configured through an extraction reaction as an anode in an electrolyser containing an electrolyte heated to a temperature of 600 to 900°C forming a molten electrolyte. The refined titanium-aluminium-vanadium alloy product is deposited on the cathode and recovered from the reactor containing no less than 85% wt. titanium, no less than 5.0% wt. aluminium and no less than 3.0% wt. vanadium.

EFFECT: ensured production of titanium-aluminium-vanadium alloy products directly from various titanium-vanadium ores with significant reduction of the number of processing stages compared to modern methods of production of Ti-AI-V alloy.
