Stochastic 3D modeling of Ostwald ripening at ultra-high volume fractions of the coarsening phase
We present a (dynamic) stochastic simulation model for 3D grain morphologies undergoing a grain coarsening phenomenon known as Ostwald ripening. For low volume fractions of the coarsening phase, the classical LSW theory predicts a power-law evolution of the mean particle size and convergence toward self-similarity of the particle size distribution; experiments suggest that this behavior holds a...
متن کاملA phase-field model for multi-component and multi-phase systems
An alternative phase-field model is presented for the simulation of microstructure evolution in polycrystalline materials existing of multiple phases and components. The model is able to treat concurrently phase transformations, diffusion controlled coarsening (Ostwald ripening) and grain growth. The equilibrium phase fractions and compositions are introduced using appropriate thermodynamic Gib...
متن کاملEffects of coupling on turbulent gas-particle boundary layer flows at borderline volume fractions using kinetic theory
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...
متن کاملPhase-field Modeling with CALPHAD and CVM for Microstructural Evolution of Ni-base Superalloy
To perform a quantitative simulation using the Phase Field Method (PFM) in a real alloy system, a new strategy of modeling the microstructure evolution of Ni-base superalloy is proposed in the present paper. In this strategy, the Calculation Phase Diagram (CALPHAD) method and Cluster Variation Method (CVM) are combined with the PFM, in which the four sub-lattice model is used to evaluate the fr...
متن کاملPart I: Ostwald ripening theories
The physical basis behind the Ostwald ripening process for two-phase mixture has been reviewed in detail, using the various theories developed to describe this process. The Ostwald ripening, also termed second phase coarsening, is generally thought to be slow, diffusion-controlled process which occurs subsequent to phase separation under extremely small under-saturation levels. The major advanc...
