Abstract
Ordering in a binary alloy is studied by means of a molecular-dynamics (MD) algorithm which allows to reach the domain growth regime. Results are comp ared with Monte Carlo simulations using a realistic vacancy-atom (MC-VA) me chanism. At low temperatures fast growth with a dynamical exponent x>1/2 is found for MD and MC-VA. The study of a nonequilibrium ordering process wit h the two methods shows the importance of the nonhomogeneity of the excitat ions in the system for determining its macroscopic kinetics.
