FIELD: metallurgy.
SUBSTANCE: method of producing of intermetallic alloys based on titanium aluminide with increased niobium content and maximum oxygen content 0.08 %wt includes preparation of the charge containing as input materials the titanium sponge with alloying components and foundry alloy, production of the consumable electrode, its remelting with production of the intermetallic alloy ingot. As the foundry alloy the alloy shaves are used, they contain in wt %: Nb 45-55, Ti 45-55, O2+N2 - maximum 0.05, at that content by weight of the foundry alloy is 70 or 75 or 85% of total weight of the charge.
EFFECT: increased chemical uniformity of the alloy ingots based on titanium aluminide with high content of niobium, and with oxygen content to ensure high mechanical and process properties of the produced items.
