TITANIUM-BASED ALLOY AND ARTICLE MADE THEREFROM Russian patent published in 2016 - IPC C22C14/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to intermetallic titanium-based alloys intended for production of parts of gas turbine engine such as blades, discs, housing and spacers, operating at high temperatures. Ti based alloy contains in % by weight: Al 9.5-12.0, Nb 38.0-42.0, Zr 1.5-2.5, Ta 0.7-1.5, W 0.5-1.0, Mo 0.3-0.6, Si 0.1-0.25, Re 0.1-0.5, C 0.03-0.08, B 0.01-0.1, Ti and admixtures are rest. Alloy is characterised by high resistance to oxidation at temperatures higher than 700 °C.

EFFECT: reliable operation of structure made using titanium-based alloy for whole service life.
