Mechanochemical spinodal decomposition: a phenomenological theory of phase transformations in multi-component, crystalline solids

Spinodal decomposition in liquid crystalline materials

The theory of phase separation m a liquid crystal by spinodal decompoSit1on is developed The time evolution of two coupled parameters, the volume concentration (or mole fraction), and the orientational order parameter is calculated The conditions for penodic fluctuations are gJven and the structure factor for spinodal decomposition is studied

Spinodal Decomposition for Multi-component Cahn-hilliard Systems

We consider the initial stage phase separation process in multi-component CahnHilliard systems through spinodal decomposition. Relying on recent work of MaierPaape and Wanner we establish the existence of certain dominating subspaces determining the behavior of most solutions originating near a spatially homogeneous state. It turns out that depending on the initial concentrations of the alloy c...

Spinodal decomposition in two-component smectics

-A two-component smectic undergoing a demixing tran~ition to two coexisting smectic pha~es exhibits a novel spinodal pattern as observed by light ~cattering and optical microscopy. We show that this ~pinodal, characterized by a prescribed angle between the mo~t intense wavevectors and the layer normal, is the result of the instability of the baroclinic mode of two-cojnponent smectic hydrodynamics.

Non-equilibrium theory of arrested spinodal decomposition.

The non-equilibrium self-consistent generalized Langevin equation theory of irreversible relaxation [P. E. Ramŕez-González and M. Medina-Noyola, Phys. Rev. E 82, 061503 (2010); 82, 061504 (2010)] is applied to the description of the non-equilibrium processes involved in the spinodal decomposition of suddenly and deeply quenched simple liquids. For model liquids with hard-sphere plus attractive ...
