This work investigates the effect of rejuvenation heat treatment, with double-step solution treatment at the temperature from 1150 °C to 1200 °C, on the recovered microstructure of IN-738 cast superalloy. The superalloy has been long-term exposed as a turbine blade in a gas turbine prior to this study.

Full Rejuvenation Heat Treatment of GTD 111DS
Volume 7: Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications, 2022Abstract Previous studies performed by TEServices, Sulzer and EPRI showed that GTD111 DS metallurgical and mechanical [stress rupture (SR) and low cycle fatigue (LCF)] properties can be restored close to new with and without hot isostatic pressing (HIP) followed by full solution heat treatment (FSHT).

Full Rejuvenation Heat Treatment of MGA 1400DS
Volume 8: Industrial and Cogeneration; Manufacturing Materials and Metallurgy, 2023Abstract Directionally Solidified (DS) nickel-base superalloys have been extensively used for power generation turbine blades. These blades are exposed to high stresses and temperatures for extended periods of time and aging the microstructural and reducing the mechanical properties.

Abstract The directionally solidified Ni-based superalloy is used in gas turbine blades for advanced aircraft engines because of its high stability and favorable properties at elevated temperatures. The microstructures of superalloys degrade when they are exposed to long-term services, and the recovery of these damaged microstructures in a real ...
