Özet
Phase transformations which lead to dramatical property change are\rvery important for engineering materials. Phase-eld methods are one of the most\rsuccessful and practical methods for modelling phase transformations in materials.\rThe Cahn-Hillard phase-eld model is among the most promising phase-eld models.\rThe most successful aspect of the model is that it can predict spinodal decomposition\r(which is essential to determining the microstructure of an alloy) in a binary system.\rIt is used in both materials science and many other elds, such as polymer science,\rastrophysics, and computer science. In this study, the Cahn-Hillard phase-eld model\ris evaluated by an analytical approach using the (1=G0)-expansion method. The so-\rlutions obtained are tested for certain thermodynamic conditions, and their accuracy\rof predicting the spidonal decomposition of a binary system is conrmed.
