The paper presents a new model of the reaction diffusion in a binary system with nonequilibrium distribution of vacancies. The influence of sources/sinks of vacancies on the kinetics of the reaction diffusion is considered and analysed. Growth rate of a phase-layer thickness is larger in the case when sources and sinks of vacancies act not only on interfaces, but in the bulk of growing phase too. Account of nonequilibrium vacancies at modelling of the reaction diffusion is especially important for systems with significant difference between the diffusion mobilities of the components.

Key words: binary system, reaction diffusion, nonequilibrium vacancies, sources/sinks of vacancies, kinetics.
