Operation experience with cast rotor blades made of Russian alloys in stationary gas turbines

The article presents the results of the analysis of operation of working blades made of cast nickel alloys applied in gas turbines for power. Russian alloys having equiaxial crystallization, i.e., TsNK-7, ChS-104, ZMI-3U, ChS-70U, ChS-88U, ZhS6K, and one foreign alloy IN738LC (for comparison) are co...

Summary:The article presents the results of the analysis of operation of working blades made of cast nickel alloys applied in gas turbines for power. Russian alloys having equiaxial crystallization, i.e., TsNK-7, ChS-104, ZMI-3U, ChS-70U, ChS-88U, ZhS6K, and one foreign alloy IN738LC (for comparison) are considered.
