Nickel-based single crystal superalloys (Ni-SXs) are of great interests in aircraft industry due
to their excellent high temperature creep strength deriving from the rigid gamma/gamma …

Thermomechanical fatigue in distinct crystal orientations of nickel-base single-crystal
superalloy was studied. Crack initiation modes and damage mechanisms were …

The effective characterization of the mechanical property degradation of turbine blades in
service for an ultra-long-term had a significant impact on the service safety and maintenance …

Single crystal (SC) Ni-based superalloys undergo microstructural degradations such as
rafting and coarsening due to the extremely harsh service environment, which consequently …

The creep-fatigue interaction has been recognized as the main failure mode of most
structural components operating in the high-temperature regime. The cyclic life (N f) usually …

In this paper, we present a new approach of combining point-by-point selective powder
delivery with powder bed fusion for multiple material (metal/glass) components printing …

Directionally solidified (DS) and single crystal (SC) Ni-based superalloys inevitably
underwent microstructural degradation induced by the harsh operating environment. For the …

Hot-section components made by single crystal (SC) Ni-based superalloys with geometrical
discontinuities such as film holes suffer from spatially inhomogeneous rafting of the γ'/γ …

The thickness debit often leads to uncertainty regarding the fatigue performance of laser
powder bed fusion (LPBF)-fabricated Inconel 718 thin-walled components and restricts the …

A new model is developed in order to account for the effect of microstructural degradation (ie
precipitate-directional-coarsening) on the viscoplastic behavior of single crystal superalloys …
