Abstract
We study the cyclic strength and durability of service-exposed turbine blades made of IN-738, ZMI-3U, and ÉP539LM nickel alloys, some of them with a protective coating, upon a long operating time in gas turbine compressor sets. The blades of IN-738 alloy are found to have the highest cyclic strength. The cyclic strength of uncoated IN-738 blades is about 10% higher than that of coated blades.
