Unified Theoretical Framework for Polycrystalline Pattern Evolution
Ari Adland, Yechuan Xu, Alain Karma
The rate of curvature-driven grain growth in polycrystalline materials is well-known to be limited by interface dissipation. We show analytically and by simulations that, for syste…
Structural short-range forces between solid-melt interfaces
Robert Spatschek, Ari Adland, Alain Karma
We predict the structural interaction of crystalline solid-melt interfaces using amplitude equations which are derived from classical density functional theory or phase-field-cryst…
Phase-field-crystal study of grain boundary premelting and shearing in bcc iron
Ari Adland, Alain Karma, Robert Spatschek +2
We use the phase-field-crystal (PFC) method to investigate the equilibrium premelting and nonequilibrium shearing behaviors of symmetric tilt grain boundaries (GBs) at high…
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…
Phase-field-crystal model for fcc ordering
Kuo-An Wu, Ari Adland, Alain Karma
We develop and analyze a two-mode phase-field-crystal model to describe fcc ordering. The model is formulated by coupling two different sets of crystal density waves corresponding…
