FIELD: metallurgy. SUBSTANCE: invention relates to titanium-base alloy designated for using as heat-resistant material. The claimed alloy and article made of thereof components taken in the following ratio, wt.-%: aluminum, 5.5-8.0; niobium, 20.0-30.0; molybdenum, 0.5-12.0; silicon, 0.015-0.5; carbon, 0.015-0.5; boron, 0.015-0.5; yttrium, 0.01- -0.7; oxygen, 0.02-0.2; nitrogen, 0.01-0.05; hydrogen, 0.001-0.03; titanium, the balance. Proposed alloy and article made of thereof show the enhanced ductility, creeping resistance, indices of small-zinc fatigue resistance in combination with high strength, heat resistance and modulus of elasticity as compared with prototype. EFFECT: improved and enhanced properties of alloy and article. 3 cl, 1 tbl, 1 ex
