Effect of Vacancy Creation and Annihilation on Grain Boundary Motion

Autor: McFadden, G. B., Boettinger, W. J., Mishin, Y.

Interaction of vacancies with grain boundaries (GBs) is involved in many processes occurring in materials, including radiation damage healing, diffusional creep, and solid-state sintering. We analyze a model describing a set of processes occurring at

Phase field modeling of electrochemistry II: Kinetics

Autor: Guyer, J. E., Boettinger, W. J., Warren, J. A., McFadden, G. B.

Publikováno v: Physical Review E, 69, (2004) 021604

The kinetic behavior of a phase field model of electrochemistry is explored for advancing (electrodeposition) and receding (electrodissolution) conditions in one dimension. We described the equilibrium behavior of this model in [J. E. Guyer, W. J. Bo

Phase field modeling of electrochemistry I: Equilibrium

Autor: Guyer, J. E., Boettinger, W. J., Warren, J. A., McFadden, G. B.

Publikováno v: Physical Review E, 69, (2004) 021603

A diffuse interface (phase field) model for an electrochemical system is developed. We describe the minimal set of components needed to model an electrochemical interface and present a variational derivation of the governing equations. With a simple

Model of Electrochemical 'Double Layer' Using the Phase Field Method

Autor: Guyer, J. E., Boettinger, W. J., Warren, J. A., McFadden, G. B.

We present the first application of phase field modeling to electrochemistry. A free energy functional that includes the electrostatic effect of charged particles leads to rich interactions between concentration, electrostatic potential, and phase st
