Spinodal decomposition in binary mixtures
Physical Review E, 1996We study the early stage of the phase separation of a binary mixture far from its critical point of demixing. Whenever the mixture of two mutually repulsive species is quenched to a temperature below its critical point of miscibility, the effect of the enthalpic repulsive force prevails upon the entropic tendency to mix, so that the system eventually ...

Spinodal decomposition in polymer mixtures
Physical Review Letters, 1989We present the first numerical study of spinodal decomposition in polymer mixtures in three dimensions for the Flory--Huggins--de Gennes free energy, numerically integrating the time-evolution equations for the conserved order parameter. We study the time dependence of the domain size as well as the pair correlation function and structure factors for ...

Spinodal decomposition in a binary mixture
Physical Review Letters, 1992The spinodal decomposition in a critical mixture of polydimethylsiloxane and diethyl carbonate was investigated by a time-resolved light-scattering technique focusing especially on the early and intermediate stages of phase separation. A second peak in addition to the main peak was found in the higher-scattering-angle region of the spectrum ...

Spinodal decomposition in a concentration gradient
Phase Transitions, 1990The effect of global density inhomogeneities on spinodal decomposition is studied in two dimensions. We performed lattice gas simulations to show that–except for boundary effects–any spatially varying density profile is conserved during phase separation.

Spinodal decomposition during isothermal gas-solid equilibration – Its effects and implications
Acta Materialia, 2018The possibility for a system to sample non-classical chemical pathways while attempting to attain thermodynamic equilibrium under conditions of restricted kinetics has been elucidated in this work through the analogy of gas phase nitriding of iron based ...

Morphology of spinodal decomposition
Physical Review E, 1997The morphology of homogeneous phases during spinodal decomposition, i.e., the scaling of the content, shape, and connectivity of spatial structures is described by a family of morphological measures, known as Minkowski functionals. Besides providing means to determine the characteristic length scale $L$ in a statistically robust and computationally ...

Anisotropic Spinodal Decomposition
Europhysics Letters (EPL), 1991We present a modification of the Cahn-Hilliard-Cook model to describe spinodal decomposition in an anisotropic fluid mixture, such as a blend of liquid crystals or a polymer solution under an extensional flow, and solve for the early time evolution of the structure function within a linear approximation.

Spinodal decomposition: A reprise
Acta Metallurgica, 1971Tiller et al. have recently attempted(1) to reformulate the theory of spinodal decomposition. Unfortunately, the equations they propose violate the second law of thermodynamics as well as displaying other incongruities. It is shown that, even if their intentions are carried out correctly, the results are at variance with existing diffusion data.
