Zusammenfassung:	preparation of titanium alloys intended for using as constructional material at elevated temperatures. SUBSTANCE: alloy comprises, wt.%: aluminium, 4.5-7.3; molybdenum, 0.4-3.8; zirconium, 3.0-5.0; tin, 1.5-3.5; niobium, 0.5-2.0; iron, 0.04-0.28; silicon, 0.05-0.5; hadolinium, 0.01-0.2; carbon, 0.01-0.3; oxygen, 0.04-0.2; hydrogen, 0.005-0.3; nitrogen, 0.005-0.3; nitrogen, 0.005-0.04; and titanium, the balance. Claimed composition makes it possible to increase heat-resistant characteristics of alloy and products manufactured therefrom; limit of durable 100 h strength at 500 C by 30% and at 600 C by 70%; yield point (100 h) at 500 C by 80% and at 600 C by 200%. Use of said alloy makes it possible to reduce weight of components and units by 50% or more and to increase payload of aircraft. EFFECT: improved properties of titanium based alloy. 3 cl, 1 tbl
