Udimet 520 is a low precipitation strengthened nickel-based superalloy, which was designed and developed to be gas turbine blades at elevated temperatures. However, after long-term service under high stresses and temperatures, the microstructure of the turbine blades could be continually degraded.

Materials at High Temperatures, 2001
AbstractSheet materials for hot gas path components in modern land based gas turbines demand high strength over the temperature range 650–950°C and freedom from serious in-service embrittlement. This is particularly critical where a gas turbine is subject to cycling since thermal stresses can lead to the cracking of such components.

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.
