Abstract

The mathematical description of the process of spinodal decomposition in high speed diffusion has been made on the basis of hyperbolic-type equation. This model is in agreement with the theory of Cahn and Hilliard at relatively small velocity mass transfer of components. The numerical research has been done that revealed changes of domain’s boundaries caused by appearing of new phases.

Keywords: spinodal decomposition, hyperbolic diffusion
