FIELD: metallurgy.
SUBSTANCE: invention refers to heat-resistant nickel-based alloys intended for manufacture of parts of high-temperature gas turbines of gas turbine engines and gas turbine plants by means of direct crystallisation method, mainly of monocrystalline blades and other components of hot turbine path. Alloy contains the following, wt %: chrome 5.0-6.0, cobalt 6.0-8.5, molybdenum 3.5-4.5, aluminium 6.0-6.5, titanium 0.8-1.6, tungsten 1.5-3.1, tantalum 3.0-4.0, rhenium 2.0-3.0, lanthanum 0.004-0.05, cerium 0.004-0.02, boron 0.004-0.01, carbon 0.002-0.05, nickel is the rest.
EFFECT: alloy is characterised with low density, high values of long-term strength and phase stability.
