The Diffuse Interface Approach in Materials Science : Thermodynamic Concepts and Applications of Phase-Field Models

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Many inhomogeneous systems involve domains of well-de ned phases se- rated by a distinct interface. If they are driven out of equilibrium one phase will grow at the cost of the other. Examples are phase separation by sp- odal decomposition or nucleation and subsequent growth of the nucleus in the nourishing phase [139]. Another example which has often been discussed as a paradigmatic problem is that of dendritic solidi cation [29, 64, 79, 199]. The phenomenological description of these phenomena involves the de - tion of a precisely located interfacial surface on which boundary conditions are imposed. One of those boundary conditions typically yields a normal - locity at which the interface is moving. This is the so-calledsharp interface approach, adopted both in analytical and numerical studies for a variety of contexts involving a moving boundary. The origin of such a description is - ten transparent, being obtained by symmetry arguments and common sense. Artikel-Nr. 9783540004165
