FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to titanium alloys, which can be used for production of aircraft engine parts. Titanium alloy consisting of, in wt. %: 6.0 to 6.7 aluminium, 1.4 to 2.0 vanadium, 1.4 to 2.0 molybdenum, 0.20 to 0.35 silicon, 0.18 to 0.23 oxygen, 0.16 to 0.24 iron, from 0.02 to 0.06 of carbon, and the rest is titanium with random impurities. Maximum concentration of any of the elements as a random impurity present in the titanium alloy is 0.1 wt. % and the total concentration of all random impurities is equal to less than or equal to 0.4 wt. %.
EFFECT: alloy is characterized by high strength, durability at low-cycle fatigue.
