alloy metallurgy. SUBSTANCE: invention relates to composites of heat-resistant nickel-base alloys and articles made of thereof by method of directed crystallization of heat-loaded articles. Nickel-base alloy and article made of thereof comprise the following components, wt.%: chromium, 3.5-4.5; aluminum, 7.5- 9.0; tungsten, 2.0-4.0; molybdenum, 4.5-5.5; carbon, 0.21-0.63; niobium, 3.3-5.1; lanthanum, 0.001-0.01; cobalt, 0.1-5.0; nickel, the balance. The invention provides the improvement of exploitation indices of nickel-base alloy and article made of thereof in the range of temperatures 20-1200 C. EFFECT: improved properties of alloy and article. 2 cl, 2 tbl, 1 ex
