Does coarsening begin during the initial stages of spinodal decomposition?

چکیده
The initial stages of spinodal decomposition were studied by subjecting a critical blend of model polyolefins to a pressure quench and monitoring the evolution by time-resolved small angle neutron scattering. Contrary to the predictions of the widely accepted Cahn-Hilliard-Cook theory, we demonstrate that coarsening of the phase-separated structure begins immediately after the quench and occurs throughout the initial stages of spinodal decomposition.

Nanoscale Phase Evolution during Continuum Decomposition of Fe-Cr Alloys
The continuum decomposition of the Fe-Cr alloys from initial phase separation to steady-state coarsening with concentrations varying from 25 at % Cr and 30 at % Cr to 33 at % Cr aged at 750 K was studied by utilizing three-dimensional phase-field simulations. The dynamic stages of separation of nanoscale Cr-enriched α' phase were distinguished by the evolution of the volume fraction, particle n...

The dynamics of the Cahn-Hilliard equations for a ternary alloy are studied during the phase separation process. The results show a primary spinodal decomposition followed by coarsening and then possibly a secondary spinodal decomposition.
متن کاملMicrodynamics and arrest of coarsening during spinodal decomposition in thermoreversible colloidal gels.
Coarsening and kinetic arrest of colloidal systems undergoing spinodal decomposition (SD) is a conserved motif for forming hierarchical, bicontinuous structures. Although the thermodynamic origins of SD in colloids are widely known, the microstructural processes responsible for its coarsening and associated dynamics en route to arrest remain elusive. To better elucidate the underlying large-sca...
متن کاملFrom colloidal aggregation to spinodal decomposition in sticky emulsions
Aggregation mechanisms of emulsions at high initial volume fractions (φ0 > 0.01) is studied using light scattering. We use emulsion droplets which can be made unstable towards aggregation by a temperature quench. For deep quenches and 0.1 > φ0 > 0.01, the aggregation mechanism is identified as diffusion-limited cluster aggregation (DLCA). An ordering of the clusters, which is reflected by a pea...
متن کاملSpinodal decomposition and coarsening fronts in the Cahn-Hilliard equation
We study spinodal decomposition and coarsening when initiated by localized disturbances in the Cahn-Hilliard equation. Spatio-temporal dynamics are governed by multi-stage invasion fronts. The first front invades a spinodal unstable equilibrium and creates a spatially periodic unstable pattern. Secondary fronts invade this unstable pattern and create a coarser pattern in the wake. We give linea...
