Modeling displacive–diffusional coupled dislocation shearing of c0 precipitates in Ni-base superalloys
In Ni-base superalloys, superlattice extrinsic stacking fault (SESF) shearing of c0 precipitates involves coupled dislocation glide and atomic diffusion. A phase-field model is developed to study this process, in which the free energy of the system is formulated as a function of both displacement and long-range order parameter. The free energy surface is fitted to various fault energy data obta...
متن کاملInterdiffusion Behavior of Pt-Diffused γ+γ' Coatings on Ni-Based Superalloys
Platinum-diffused γ+γ' coatings (~20 at.% Al, ~22 at.% Pt) were synthesized on René 142 and René N5 Ni-based superalloys by electroplating the substrates with ~7 μm of Pt, followed by an annealing treatment in vacuum at 1175°C. In order to study the compositional and microstructural evolution of these coatings at elevated temperatures, interdiffusion experiments were carried out on coated speci...

متن کاملHigh Temperature Nanoindentation of Ni-base Superalloys
Novel techniques for characterizing and assessing the properties of Ni-base superalloys are becoming increasingly important to the accelerated development of new structural alloys and the advancement of physics-based mechanical property models. Instrumented indentation techniques have long served as a useful approach for probing the mechanical response of a wide range of engineering materials. ...
متن کاملFlow Stress Modeling in a γ-γ/ Cobalt Base Superalloy by Using the Hyperbolic Sine Equation and ANN Method
The new class of wrought γ-γ/ Co-base superalloys, which are based on Co-Al-W system, was developed by conventional hot working routes with a high volume fraction of γ/ precipitates and good mechanical properties. The aim of the present study was to predict the flow stress and hot deformation modeling of a novel γ-γ/ Co-base superalloy. The hot compression test...
