FIELD: metallurgy.
SUBSTANCE: invention refers to heat resistant cast alloys on nickel base used for fabrication of heavy duty parts, for example blades of gas turbines operating at temperature above 1000°C by methods of directed crystallising and mono-crystal casting. Alloy contains, wt %: chromium to 3.0, cobalt to 5.0, tungsten 8.0-12.0, aluminium 4.3-5.6, tantalum 9.0-13.0, rhenium 4.0-6.0, carbon 0.002-0.05, yttrium 0.003-0.1, lanthanum 0.001-0.2, cerium 0.003-0.1, neodymium up to 0.01, scandium 0.05-0.1, silicon 0.05-1.0, magnesium 0.01-0.15, nickel - the rest.
EFFECT: increased high temperature durability and heat resistance of alloy.
