Abstract The morphological evolution of γ′ precipitates for a damaged nickel‐based superalloy GTD‐111 under different rejuvenation heat treatments (RHTs) was investigated. The degenerated γ′ precipitates can be completely dissolved into the γ matrix under the full solution condition of 1200 °C/2 h, and only fine γ′ precipitates re ...

The rejuvenation procedures to recover the creep properties of nickel-base superalloys by atmospheric pressure heat treatment and hot isostatic pressing techniques have been reviewed in detail. It is very important that such treatments be applied at an optimum stage in the service life of a turbine blade.

Abstract Single crystal superalloys are widely used for gas turbine blades exposed to high stresses, high temperatures in aggressive environments. When these components reach their serviceable limit, they must be replaced by new ones, with an important impact in terms of maintenance costs.
