A crystal viscoplasticity (CVP) model for the creep-fatigue interactions of nickel-base
superalloy CMSX-8 is proposed. At the microstructure scale of relevance, the superalloys …

Nickel-based single crystal creep's properties are commonly calculated according to the
rupture strength under constant load. The creep deformation of turbine blades is not only …

A phenomenological hardening-based damage density function built on a Rabotnov-
Kachanov's formulation and coupled to a microstructure-sensitive viscoplastic crystal …

In Ni-based single crystal superalloys, the macroscopic properties are intertwined with their
complex bi-phased γ (NiAl)/γ'(Ni 3 Al) microstructure. This study aims to better understand …

Micro-mechanical response to overheating events is an important factor when considering
the serviceable life of aero-engine components. A key lifing consideration is the low-cycle …

The low cycle fatigue (LCF) characteristics of nickel-based single crystal (SC) superalloy
have been experimentally and numerically investigated. The effects of crystallographic …

The work discusses the complex thermo-mechanical approaches developed at ONERA
within the context of gas turbine component fatigue tests. Emphasis is placed on the general …

The fatigue crack initiation transition from internal defects to the surface at high temperatures
has been thefocus of this study. The new challenges resulting from the increase in …

In this paper, a single crystal (SC) partition model, consisting of primary grains and grain
defects, is proposed to simulate the weakening effect of grain defects generated at …

The mechanical response of Ni-based single-crystal superalloys is known to be sensitive to
the microstructural state, ie, the shape and size of the γ′ precipitates when exposed to high …
