Directionally solidified gas turbine blades are wildly used in land-based industrial gas
turbines for power generation. During long-term service, the harsh service environment …

Ni-base single-crystal turbine blades are exposed to a combination of high temperatures
and high stresses during their service life in high-pressure turbines of aero engines or …

In the present work, we study the effect of HIP rejuvenation treatments on the creep behavior
and residual life of a pre-crept single crystal Ni-base superalloy of type CMSX-4. The …

The repair of R26 high-temperature alloy bolts with excessive hardness after∼ 60,000 h of
service using rejuvenation heat treatment was evaluated. Stress relaxation tests with …

Rejuvenation of the initially hot isostatic pressing (HIP) heat-treated single-crystal Ni-base
superalloy (SX) ERBO/1 was examined experimentally and via phase field simulation to …

Both surface and internal microstructures of a second-generation Ni-based single crystal
(SX) superalloy were studied after creep and rejuvenation heat treatment (RHT). It is …

During service, superalloy turbine components degrade over time by creep and fatigue
deformation mechanisms due to a complex combination of stresses at high temperatures …

Academic debate still exists as to whether and how multi-scale microstructure recovery is
linked to creep properties rejuvenation of superalloys. We propose a rejuvenation heat …

Directionally solidified (DS) Ni-based superalloys are widely used in gas turbine blades due
to excellent mechanical properties for elevated temperature applications. In harsh service …

The recovery of microstructure and creep properties of a directionally solidified superalloy
after long-term thermal exposure was investigated. After reheat treatment, successful …
