Effect of Heat Treatment on Microstructure and Mechanical Properties of GH4169 Superalloy

Rare Metal Materials and Engineering, 2014
Abstract The effects of the solution and aging treatment on the microstructure, the tensile properties at room-temperature and 650 °C and the stress rupture of GH4169 superalloy were investigated. The results show that after solution at 980 °C and aging at 720 °C plus 620 °C, both the yield strength and ultimate strength of the superalloy at room ...

Properties of NiCrAlY coatings fabricated on superalloy GH4169 by electrospark deposition

The International Journal of Advanced Manufacturing Technology, 2017
NiCrAlY coatings were deposited on superalloy GH4169 by electrospark deposition technique. Influences of the depositing parameters (100 V/40 μF, 100 V/80 μF, 100 V/120 μF, 150 V/40 μF, 150 V/80 μF, 150 V/120 μF) on the microstructure and the properties of the coatings were experimentally investigated.

Solute atom migration in GH4169 superalloy under electrostatic fields

International Journal of Minerals, Metallurgy, and Materials, 2013
Electric field treatment (EFT) was applied on GH4169 alloy during aging at 500–800°C to investigate the microstructure and property variation of the alloy under the action of EFT. The results demonstrate that the short-distance diffusion of Al, Ti, and Nb atoms can be accelerated by EFT, which results in the coarsening of γ′ and γ″ phases.
