INTERMETALLIC TITANIUM-BASED ALLOY

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to intermetallic alloy based on titanium type Ti₂AlNb, and can be used for the manufacture of an aircraft turbine parts. Intermetallic titanium-based alloy contains, at %: Al from 22 to 25, Nb from 20 to 22, metal M, selected from Mo, W, Hf and V, to 3, Si from 0.1 to 0.5, Ta from 0 to 2, Zr from 1 to 2, Fe+Ni≤400 million^-1 the rest is Ti, with the following condition: Al/Nb ratio of 1.05 to 1.15.;EFFECT: alloy is characterized by high oxidation resistance at high temperature.;6 cl, 2 tbl, 4 ex, 3 dwg
