High temperature structure stability of GH4169 superalloy
Materials Science and Engineering: A, 2013Abstract The long-term thermal stability of GH4169 superalloy has been studied as a function of heat treatment and thermal exposure. The GH4169 superalloy was subjected to long-term unstressed heat treatment at 650 °C, from 200 to 1000 h. The microstructure, tension and stress rupture properties of the samples before and after long-term thermal ...

Creep-fatigue crack growth behavior in GH4169 superalloy
Frontiers of Mechanical Engineering, 2017This study aims to examine the crack growth behavior of turbine disc GH4169 superalloy under creep-fatigue loading. Crack growth experiments were performed on compact tension specimens using trapezoidal waveform with dwell time at the maximum load at 650 °C. The crack growth rate of GH4169 superalloy significantly increased with dwell time.

Deformation behaviour of GH4169 nickel based superalloy in isothermal compression
Materials Science and Technology, 2008Isothermal compression of the GH4169 nickel based superalloy was carried out at a Thermecmaster-Z simulator at deformation temperatures of 930–1050°C at intervals of 20°C, strain rate of 0·1–50·0 s−1 and maximum height reduction of 60·0%. The deformation behaviour of the GH4169 superalloy in isothermal compression was characterised based on the stress–
