In this paper we present the results of modeling of the sex shop arles reaction diffusion in fcc structure between pure component A and orderedphase A<sub>1</sub>B<sub>1</sub> using the kinetic mean-field method.Theformationtime of the ordered phase A<sub>3</sub>B<sub>1</sub> (incubation time) exponentially depends on the asymmetry of the system.On the base of the kinetic mean-field method the tracer diffusion coefficients in the ordered phase A<sub>3</sub>B<sub>1</sub> weredetermined.Based on the computer experiments and theoretical considerations the constant of phase growth has been determined.
