Model of spinodal decomposition of phases under hyperbolic diffusion

Abstract

A model is proposed for the kinetics of spinodal decomposition at high diffusion rates described by a hyperbolic equation. The formation of new phases is described using a zero-radius nonlinear potential model. It is shown that a regular distribution in space of the phases during spinodal decomposition is initiated by suitable initial conditions for the concentration gradient with constant initial concentrations of the components.
