Domain growth in a two-dimensional binary alloy was studied by means of Monte Carlo simulation of an ABV model. The dynamics consists of exchanges of particles with a small concentration of vacancies. The influence of changing the vacancy concentration and finite-size effects was analyzed. Features of the vacancy diffusion during domain growth were also studied. The anomalous character of the diffusion due to its correlation with local order was responsible for the obtained fast-growth behavior.
