摘要
The special characteristics of structure and phase transformations in nickel based superalloys after long high-temperature holds are discussed. The formation of TCP-phases with different morphology is known to be the main feature of the investigated alloys. The residual short-term mechanical properties study after holds are determined. It is shown that the destruction of the specimen with different morphology TCP-phases occurs due to the formation and development of cracks along the gamma'/TCP-interface. Nano-phase hardening of single-crystal nickel alloys is considered. (C) 2015 Elsevier B.V. All rights reserved.
