A phase field model with arbitrary misorientation dependence of grain boundary energy
Philip Staublin, Yuri Mishin, Peter W. Voorhees +1
Grain growth in polycrystals is often simulated using orientation-field models, which employ a field to represent the local orientation of the crystal lattice. These models can be…
Thermal Equilibrium Vacancy Concentration in an Alloy with Chemical Short-Range Order
Hao Tang, Hoje Chun, Rafael Gomez-Bombarelli +2
The equilibrium vacancy concentration in multi-principal element alloys remains a controversial and nontrivial subject, primarily because of chemical complexity and chemical short-…
A model of thermodynamic stabilization of nanocrystalline grain boundaries in alloy systems
Omar Hussein, Yuri Mishin
Nanocrystalline (NC) materials are intrinsically unstable against grain growth. Significant research efforts have been dedicated to suppressing the grain growth by solute segregati…
Effect of Vacancy Creation and Annihilation on Grain Boundary Motion
G. B. McFadden, W. J. Boettinger, Y. Mishin
Interaction of vacancies with grain boundaries (GBs) is involved in many processes occurring in materials, including radiation damage healing, diffusional creep, and solid-state si…
Irreversible thermodynamics of creep in crystalline solids
Y. Mishin, J. A. Warren, R. F. Sekerka +1
We develop an irreversible thermodynamics framework for the description of creep deformation in crystalline solids by mechanisms that involve vacancy diffusion and lattice site gen…
Effect of interface phase transformations on diffusion and segregation in high-angle grain boundaries
T. Frolov, S. V. Divinski, M. Asta +1
Recent experimental measurements of Ag impurity diffusion in the Σ5 (310) grain boundary (GB) in Cu revealed an unusual non-Arrhenius behavior suggestive of a possible structural t…
Thermodynamics of coherent interfaces under mechanical stresses. I. Theory
T. Frolov, Y. Mishin
We present a thermodynamic theory of plane coherent solid-solid interfaces in multicomponent systems subject to nonhydrostatic mechanical stresses. The interstitial and substitutio…
Coupled motion of asymmetrical tilt grain boundaries: molecular dynamics and phase field crystal simulations
Z. T. Trautt, A. Adland, A. Karma +1
Previous simulation and experimental studies have shown that some grain boundaries (GBs) can couple to applied shear stresses and be moved by them, producing shear deformation of t…
