Creep-fatigue life prediction in nickel-based superalloy GH4169 based on microstructural damage quantification with the help of electron backscatter diffraction

Creep-fatigue life prediction in nickel-based superalloy GH4169 based on microstructural damage quantification with the help of electron backscatter diffraction

A series of strain-controlled creep-fatigue tests under different loading waveforms are carried out on GH4169 superalloy at 650 °C. In the macroscopic view, a unified viscoplastic constitutive framework is used to describe cyclic deformation process. Particularly, a modified kinematic hardening rule...
