Journal ArticleDOI
Free Energy of a Nonuniform System. I. Interfacial Free Energy
John W. Cahn,John E. Hilliard +1 more
TL;DR: In this article, it was shown that the thickness of the interface increases with increasing temperature and becomes infinite at the critical temperature Tc, and that at a temperature T just below Tc the interfacial free energy σ is proportional to (T c −T) 3 2.
Journal ArticleDOI
Metallic Phase with Long-Range Orientational Order and No Translational Symmetry
TL;DR: In this article, a metallic solid with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations, was observed and its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice.
Journal ArticleDOI
On spinodal decomposition
TL;DR: In this article, the stability of a solid solution to all infinitesimal composition fluctuations is considered, taking surface tension and elastic energy into account, and it is found that for infinite isotropic solids, free from imperfections, the spinodal marks the limit of metastability to such fluctuations only if there is no change in molar volume with composition.
Journal ArticleDOI
A microscopic theory for antiphase boundary motion and its application to antiphase domain coarsening
Samuel M. Allen,John W. Cahn +1 more
Journal ArticleDOI
Free Energy of a Nonuniform System. III. Nucleation in a Two‐Component Incompressible Fluid
John W. Cahn,John E. Hilliard +1 more
TL;DR: In this article, the saddle point in the expression derived in Paper I (see reference 8) for the free energy of a nonuniform system was used to derive the properties of a critical nucleus in a two-component metastable fluid.
