Résumé : The thermodynamic analysis of the morphological stability of a planar solidification front during the unidirectional growth from the melt of a dilute binary alloy is developed on the basis of the Glansdorff-Prigogine theory extended for surfaces. The surface excess entropy balance is derived. The obtained explicit criterion gives the physical meaning of the stabilizing and destabilizing contributions. The link with the kinetic approach is discussed for the phase interface and the multilayer models. © Copyright 1982, by Walter de Gruyter & Co.
