Theory of diffusive decomposition of supersaturated multicomponent systems

A closed system of equations, which describes the evolution of supersaturated multicomponent solutions, is obtained. A general solution of these equations is determined in the late stage of decomposition, which is determined by nonlinear diffusive interaction of macrodefects.The algebraic equations, which determine the coexistent phases, are obtained.The size of distribution function for particles is determined for each phase. The boundaries of the coexistent phases are defined.
