FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly to titanium-based alloys. High-temperature titanium-based alloy contains, wt%: aluminium from 4.5 to 7.5; tin from 2.0 to 8.0; niobium from 1.5 to 6.5; molybdenum from 0.1 to 2.5; Silicon from 0.1 to 0.6; titanium - balance.
EFFECT: alloy is characterised by high corrosion resistance, mechanical strength at high temperatures of up to 750 °C, weldability, as well as high characteristics of ability to deformation in hot/cold state and to superplastic formation.
