Abstract

We present results concerning the study of growth and coarsening kinetics of ordered domains in a binary alloy exhibiting a B2 ordering at the stoichiometric composition. This study has been performed within the framework of an atomistic kinetic model based on vacancy migration using Monte Carlo simulations techniques. Contrary to the standard Lifshitz-Allen-Cahn law, it is observed that the coarsening exponent is a function of the annealing temperature, and also of parameters controlling the migration of the vacancy.
