摘要：

A microscopic calculation was carried out for spinodal decomposition in the tetragonal TiO2-SnO2 system by taking into account the contribution of the elastic free energy. Necessary elastic constants for the solid solutions and the elastic free energy of modulated structure were calculated in terms of interatomic potentials. A coherent phase diagram was obtained unambiguously from the calculated elastic free energy by using the interaction parameter determined by the experimental binodal line. The results were compared with the calculation based on the regular-solution model.
