Due to the outstanding creep performance, nickel-based single crystal superalloys (Ni-SXs)
are extensively applied in modern aero-engine and industrial gas turbine. Apart from the …

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 …

Tension-compression asymmetry is a common phenomenon in the deformation behavior of
nickel-based superalloys, and a thorough understanding of this phenomenon is essential …

Re is one of the newly added key elements of single crystal Ni-based superalloys for
advanced aero-engine turbine blades. The mechanisms that how Re influences the …

In the present work, we propose a novel model coupling phase-field, dislocation density
based plasticity and damage. The dislocation density governing equations are constructed …

Surface treatment techniques, like laser peening, enhance the longevity of Ni-based
superalloy components by reinforcing their microstructure against surface-initiated damage …

Topological phase inversion, in which γ'-precipitate becomes topological matrix phase, is a
typical 'detrimental'microstructural degradation in Ni-based single-crystal superalloys. Here …

Co-base superalloys show attractive properties for the strengthening of γ'-Co 3 (Al, W)
precipitates. Directional coarsening of γ'precipitates under external stress forms the rafting …

Microstructure evolution occurs throughout the high temperature creep process inside nickel-
based single crystal superalloys. In this study, creep tests of a nickel-based single crystal …

The initial γ/γ′ microstructure (eg γ′ shape, size, volume fraction) may dramatically affect
creep behaviour of single crystal Nickel-based superalloys. However, it is difficult to have …
