Johnson, William C.; Voorhees, P. W. Interfacial stress, interfacial energy, and phase equilibria in binary alloys. (English) Zbl 0952.74005 J. Stat. Phys. 95, No. 5-6, 1281-1309 (1999). Summary: A model is presented to explore the influence of interfacial stress, interfacial energy, and surface stress on the characteristics of phase equilibria in stressed, two-phase binary alloys. Two different system geometries are employed: concentric spheres and thin plates. The conditions for thermodynamic equilibrium are solved, and equations of state for each geometry are obtained in terms of phase fraction, alloy composition, system dimension, and several dimensionless material parameters. Elastic stress introduces new equilibrium states that are further modified by the interfacial quantities. Those conditions are identified for which interfacial quantities can induce significant changes in the equilibrium phase fraction and phase compositions.
