The dynamics consists of exchanges of particles with a small concentration of vacancies. The influence 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-growth behavior.6 p.application/pdfeng(c) The American Physical Society, 1993Transformacions de fase (Física estadística)Diagrames de faseTermodinàmicaMètode de MontecarloPhase transformations (Statistical physics)Phase diagramsThermodynamicsMonte Carlo methodMonte Carlo study of the relation between vacancy diffusion and domain growth in two-dimensional binary alloysinfo:eu-repo/semantics/article87908info:eu-repo/semantics/openAccess
