FIELD: metallurgy.
SUBSTANCE: invention relates to production of heat-resistant titanium-based alloys used for manufacture of wide range of deformed semi-finished products and parts. Heat-resistant titanium-based alloy contains, wt%: aluminium is 10.5-12.5; niobium is 38.5-42.0; molybdenum is 0.5-1.5; vanadium is 0.5-1.5; zirconium is 1.0-2.5; tungsten is 0.3-1.0; tantalum is 0.3-1.0; silicon is 0.1-0.25; gadolinium is 0.02-0.6; titanium and admixtures are rest.
EFFECT: alloy is characterised by high values of strength at room and high temperatures of up to 700 °C.
