Zusammenfassung:	FIELD: metallurgy.SUBSTANCE: versions of single-crystalline superalloy are proposed on the basis of Ni, as well as a turbine blade, where it is used. The alloy contains the following components, wt %: Co 0.0-15.0, Cr 4.1 - 8.0, Mo 2.1 - 4.5, W 0.0 - 3.9, Ta 4.0 - 10.0, Al 4.5 - 6.5, Ti 0.0 - 1.0, Hf 0.00 - 0.5, Nb 0.0 - 3.0, Re 8.1 - 9.9, Ru 0.5 - 6.5, Ni and unavoidable admixtures - balance.EFFECT: alloy has high specific creep resistance in high-temperature media, and a turbine blade has low specific weight and may be operated at high temperatures.13 cl, 4 dwg, 1 tbl, 28 ex Изобретение относится к области металлургии, в частности к монокристаллическим суперсплавам на основе никеля. Заявлены варианты монокристаллического суперсплава на основе Ni и лопатка турбины, в которой он использован. Сплав содержит, мас.%: Со 0,0-15,0, Cr 4,1-8,0, Мо 2,1-4,5, W 0,0-3,9, Та 4,0-10,0, Al 4,5-6,5, Ti 0,0-1,0, Hf 0,00-0,5, Nb 0,0-3,0, Re 8,1-9,9, Ru 0,5-6,5, Ni и неизбежные примеси - остальное. Сплав имеет высокое удельное сопротивление ползучести в высокотемпературных средах, а лопатка турбины - малый удельный вес и может эксплуатироваться при высоких температурах. 11 н. и 2 з.п. ф-лы, 5 ил., 1 табл., 28 пр.
