FIELD: metallurgy.
SUBSTANCE: invention refers to intermetallic alloys on the basis of titanium, which are intended for manufacture of compressor parts of gas-turbine engine, for example such as blades, discs, inserts, housings, which work at increased temperatures. There proposed is intermetallic titanium-based alloy having the following chemical composition, wt %: Al 10.5-12.5, Nb 38-42, Mo 0.3-0.6, Zr 1.5-2.5, Si 0.1-0.25, C 0.03-0.08, W 0.5-1.0, Ta 0.7-1.5, and Ti is the rest. Alloy is characterised with increased fire resistance at temperature of up to 700°C.
EFFECT: service life of parts increases and reliable operation of the construction is provided.
