Abstract
Domain growth in a two-dimensional binary alloy is studied by means of Monte Carlo simulation of an ABV model. The dynamics consists of exch anges of particles with a small concentration of vacancies, The influe nce of changing the vacancy concentration and finite size effects has been analyzed. Features of the vacancy diffusion during domain growth are also studied. The anomalous character of the diffusion due to its correlation with local order is responsible for the obtained fast-grow th behavior.
