Abstrakt: The studies directed on designing an advanced rhenium-free nickel superalloy, which is an analog of ZhS32VI alloy, are performed. The chemical composition of the alloy has been found and an experimental alloy batch has been melted (10 kg). Microstructural and metallographic studies and strength tests are carried out. The new single-crystal superalloy has a long-term strength σ = 238-248 MPa at a density of 8.87 g/cm. [ABSTRACT FROM AUTHOR]
