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 |
