FIELD: nonferrous metallurgy.
SUBSTANCE: invention provides heat-resistant alloy having monocrystalline structure and articles fabricated therefrom, in particular gas turbine blades. Alloy is composed of, wt %: chromium 2.1-3.3, cobalt 5.0-7.0, molybdenum 3.5-5.0, tungsten 3.2-4.8, tantalum 4.0-5.0, rhenium 5.6-7.0, ruthenium 2.0-6.0, aluminum 5.7-6.3, carbon 0.002-0.02, boron 0.0004-0.004, yttrium 0.002-0.02, cerium 0.001-0.02, lanthanum 0.002-0.25, neodymium 0.0005-0.012, nickel - the rest. Alloy is characterized by density 8.8-9.9 g/cm3, high phase stability and improved heat resistance within temperature range 1100-1150°C.
EFFECT: improved performance characteristics of alloy.
