Zusammenfassung:	FIELD: metallurgy. SUBSTANCE: nickel-base alloy has the following components, wt. -%: carbon 0.005-0.12; chrome 13.5-14.5; cobalt 8.0-12.0; tungsten 3.0-5.0; molybdenum 1.5-2.5; titanium 3.4-4.3; aluminium 3.5-4.8; niobium 0.4-1.4; tantalum 0.2-1.0; hafnium 0.1-0.4; boron 0.001-0.02; yttrium 0.005-0.05 and nickel - the rest. Alloy is designated for making the gas turbine high-temperature unit articles exhibiting the directed and monocrystalline structures by method of the directed crystallization at high yield of ingots (by macrostructure data). EFFECT: improved quality and properties of the alloy. 2 tbl
