FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy. Titanium-based alloy comprises the following, wt %: aluminum 4.5-6.5, vanadium 1.0-3.0, iron 0.5-2.5, gadolinium 0.2-0.6, silicon 0.003-0.15, oxygen 0.003-0.15, titanium is the rest. The alloy has high yield tensile strength properties at the temperature of 20°C as well as a sound structure and a reduced tendency to embrittlement during operation at the temperatures of -70 to +400°C.
EFFECT: creation of structural titanium alloys for manufacture of medium loaded parts which are used among other things for an aircraft glider kit operating at the temperatures from -70 to +400°C.
