Having regard to the inherent crystal anisotropy characteristic of nickel-based single crystal
and the actual industrial manufacture, and application of the turbine blade, a trade-off …

The prediction of the viscoplastic behavior of nickel-based single crystal superalloys
remains a challenging issue due to the complex loadings encountered in aeronautical …

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

The morphological evolution of the γ′ precipitates has been studied in a second generation
nickel-based single crystal superalloy during isothermal creep straining at 1093° C under …

Dramatic temperature changes will lead to uneven expansion and contraction, and then
create transient stress cycles that inevitably result in thermal fatigue damage. In this study …

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 …

It is acknowledged that voids are unavoidable manufacture defects influencing the
microstructure evolution and mechanical properties of nickel-based superalloys. The …

Creep damage by void nucleation and growth limits the lifetime of components subjected to
mechanical loads at high temperatures. For the first time, the porosity of a Ni-based single …

The elastic properties of the single-crystal nickel-base superalloy CMSX-4 used as a blade
material in gas turbines were investigated by the sonic resonance method in the …

The low cycle fatigue behavior of a directionally solidified nickel-based superalloy DZ125
was examined at 850° C in air using bare and salt-coated specimens. Experimental results …
