摘要：
The stability of multilayers at elevated temperatures is investigated by simulating the evolution of the concentration profiles within the framework of the Cahn-Hilliard theory. For immiscible binary systems, a permanent layer thickness coarsening perpendicular to individual layers occurs by dissolution of the thinnest layers. With advancing layer coarsening, this one-dimensional coarsening mechanism slows down strongly. Comparatively rapid multilayer decomposition is caused by lateral inhomogeneities in individual layers. Possible mechanisms of the formation of 'holes' consisting of one phase in layers of the other phase are proposed and subsequent hole growth is studied within a two-dimensional model.
