The equations of spinodal decay in binary systems in which there is a phase transition-improper decay are obtained. For the first time, spinodal equations for a phase transition with one multicomponent order parameter (two one-component) are obtained.

The paper presents a theoretical study of spinodal and binodal decomposition of binary solutions. Since there is no thermodynamic barrier in spinodal decomposition, phase decomposition is determined only by diffusion. Thus, at decay many features of phase decomposition can be described by the analytical solution. The equations of spinodal and binodal decomposition in solutions without structural phase transitions are obtained.
