Influence of model asymmetry on kinetic pathways in binary Fe-Cu alloy: a kinetic Monte Carlo study

摘要

A kinetic Monte Carlo simulations with model asymmetry in binary Fe-Cu alloyleading to the same microstructure are presented. A method based onthermodynamic data for calculation of interatomic potentials dependent on modelasymmetry is presented and evaluated. Results show that kinetic pathways aresensitive to model asymmetry and are compared to the classical growth andcoarsening theories. Experimental diffusion data is used and compared tosimulation results to determine a realistic combination for simulations.
