Fatigue crack paths in single-crystal Ni-base superalloys do not follow the classical Stage
I/Stage II behavior. In fact, the opposite often occurs with cracks growing initially in Mode I …

Traditional probabilistic fatigue life test requires long time, a large number of samples and
high cost due to dispersion, randomness and complexity. A new data-driven probabilistic …

Abstract Effects of grain boundaries (GBs) on fatigue crack propagation (FCP) in a cast Ni-
base superalloy were experimentally investigated using “two-dimensional” polycrystalline …

The mechanistic basis of microstructurally short crack paths and growth rates is investigated
in Ni-based superalloy single crystals using Crystal Plasticity (CP) and eXtended Finite …

The plastic deformation behavior of three various orientation specimens of a nickel-based
single-crystal (SX) superalloy were investigated by in-situ electron back-scattered diffraction …

This work studied the relationship between the fatigue behavior and microstructural
evolution of a second-generation nickel-based single-crystal superalloy with [001],[102], and …

Mechanistic short crack growth in single crystal Ni γ− γ′ microstructure is investigated using
Crystal Plasticity (CPFEM) and eXtended Finite Element Method (XFEM). Maximum slip and …

Understanding the deformation behavior of Ni-based superalloy IN718 across various
temperature ranges is crucial due to its working temperature variability, despite its primary …

单晶镍基合金具有优异的耐高温, 高强, 高韧等性能, 这些力学性能受制造过程引入的次级取向和
冷却孔的影响. 已有研究大多关注单孔薄板的变形机理和力学性能, 而工程中应用的往往是多孔 …

In this study, a microdamage model is newly proposed to predict the failure process of FCC
single crystals. Two micro damage mechanisms, slip and cleavage, are both involved in the …
