Modeling Creep-Fatigue Deformation of Ni-Base Superalloys Using Crystal Viscoplasticity

CODEN: JAIOAD

Abstract

Crystal viscoplasticity enables one to correctly capture the anisotropic inelastic behavior of single crystal and directionally solidified alloys as well as the microstructural sensitivity in polycrystalline alloys. This paper reviews several physics-based crystal viscoplasticity models that have been established to predict the deformation response of Ni-base superalloys. The attributes of crystal viscoplasticity models necessary for predicting the creep-fatigue deformation are identified. Several new developments in constitutive modeling of Ni-base superalloys are discussed.
