FIELD: metallurgy.
SUBSTANCE: nickel-based alloy containing the following, wt %, is proposed: Co 2.75-3.25, Cr 11.5-12.5, Mo 2.75-3.25, Al 3.75-4.25,Ti 4.1-4.9, Ta 1.75-2.25, C 0.006-0.04, B ≤ 0.01, Zr ≤ 0.01, Hf ≤ 1.25, Nb ≤ 1.25, and Ni is the rest. Alloy can be used for manufacture at least of some part of blade or for manufacture of gas turbine blade.
EFFECT: alloy is characterised with high creep strength.
