FIELD: metallurgy.
SUBSTANCE: invention can be used to manufacture highly loaded rotor parts operating at temperatures up to 650-700°C in gas-turbine engines. The high-temperature nickel alloy contains, wt %: carbon 0.08-0.15; chrome 10.5-12.5; cobalt 14.0-16.0; tungsten 4.0-6.0; molybdenum 2,6-3,6; titanium 2.5-3.5; aluminium 3,6-4,6; niobium 3.0-4.0; tantalum 0.1-1.3; hafnium 0.05-0.2; vanadium 0.1-0.5; boron 0,005-0,05; zirconium 0,001-0,05; cerium 0,001-0,05; scandium 0.01-0.1; magnesium 0.001-0.05; the rest is nickel and inevitable impurities.
EFFECT: alloy has high strength and high-temperature strength, has a high resistance of low-cycle fatigue.
