Isothermal and bithermal thermomechanical fatigue behavior of a NiCoCrAlY-coated single crystal superalloy [PDF]

Specimens of single crystal PWA 1480 with group of zone axes (100) orientation, bare, or with NiCoCrAlY coating PWA 276, were tested in low cycle fatigue (LCF) at 650, 870, and 1050 C, and in simplified bithermal thermomechanical fatigue (TMF) tests ...

Effect of carbon content on solidification behavior of a Mo- and Al-rich nickel-based single-crystal superalloy

Materials & Design
Optimizing carbon content is critical for the design of Ni-based single-crystal superalloys, particularly for high-temperature applications. This study systematically investigated the influence of carbon on the solidification behavior and phase evolution

Micromechanics of cyclic deformation in SSME turbopump blade materials [PDF]

Current and candidate Space Shuttle Main Engine (SSME) turbopump blade materials are anisotropic, both in their elastic and plastic response. The major objective is to characterize the plastic deformation behavior of a typical single crystal nickel-base ...

Improving oxidation resistance property of single-crystal Ni-based superalloy via utilizing high temperature aging-induced dislocations

Journal of Materials Research and Technology
It is hard to improve the oxidation resistance property of single-crystal (SC) Ni-based superalloys except for alloying design since monocrystalline lacks defects such as grain boundaries that are beneficial for antioxidant elemental diffusion. This work

Influence of composition on the microstructure and mechanical properties of a nickel-base superalloy single crystal [PDF]

The effects of cobalt, tantalum, and tungsten contents on the microstructure and mechanical properties of single crystal Mar-M247 were investigated. Elevated temperature tensile and creep-rupture properties of 001 oriented single crystals were related ...

Discrete dislocation dynamics simulations of dislocation-$\theta'$ precipitate interaction in Al-Cu alloys

, 2018
The mechanisms of dislocation/precipitate interaction were studied by means of discrete dislocation dynamics within a multiscale approach. Simulations were carried out using the discrete continuous method in combination with a fast Fourier transform ...
