| Abstract Scope |
The Cahn-Hilliard equation has been successfully applied to study spinodal decomposition. In this work, we propose an extension of this approach to the nucleation and growth process. The approach we propose differs from Simmons' in that the nucleation process is calculated in a self-consistent manner. Thus, nucleation processes no longer suffer from the usual and well-known limitations of classical nucleation theory. This approach can then be applied far from the solubility limit, in the miscibility gap where experimental measurements can be performed. This work proposes an alternative to Binder's approach to the nucleation process, highlighting the physical reason responsible for the transition between nucleation and growth regimes and spinodal decomposition. |
