Poduri and Chen [29] studied the nucleation of an ordered precipitate from a disordered matrix by extending the diffuse-interface theory of Cahn and Hilliard. Roitburd [31] and Chu et al. [5] were the first to explore the nucleation of martensites using the non-clas- sical approach. ...
We review the diffuse interface model for fluid flows, where all quantities, such as density and composition, are assumed to vary continuously in space. This approach is the natural extension of van der Waals' theory of critical phenomena both for one-component, two-phase fluids and for liquid...
The model proposes that nucleation sites for cavitation are gas pockets trapped at the base of defects (cracks) located at the solid-liquid interface. In a previous paper (Smith and Ewers, 2002a) postulated that the presence of a diffuse double layer would suppress cavity cavitation behaviour ...

A diffuse interface theory of nucleation proposed recently for vapor condensation and crystal nucleation is compared with experiments and field-theoretical models of nucleation. Without adjustable parameters the theory gives an improved description of condensation experiments on non-polar and weakly polar ...
A diffuse interface theory (DIT) of nucleation is applied for the crystallization of various oxide glasses showing volume nucleation. It is demonstrated that, in contrast with the classical theory which often yields "anomalous" nucleation prefactors, the DIT is consistent with the experiments. A ...
A diffuse interface theory of nucleation is proposed on the basis of a parametrization of the cross-interfacial enthalpy and entropy distributions, relating thus the excess free energy of nuclei to macroscopic quantities. The model is applied for vapour condensation, to crystal nucleation form liqiud ...
crystal nucleationphenomenological diffuse interface theoryreviewRecent developments in the phenomenological diffuse interface theory of nucleation are reviewed. The applicability for vapor condensation is demonstrated. The diffuse concept is applied for crystal nucleation in melts and glasses. The temperature ...
To circumvent these problems a simplified theory of homogeneous nucleation (DIT) that accounts for the diffuseness of the interface has been proposed recently. The new approach led to an improved description of vapor condensation and crystal nucleation from a glass. In the present work this model ...
