Process by which phase domains increase in size during the aging of a multiphase material.
Notes:
- In the coarsening at the late stage of @[email protected], volumes and compositions of phase domains are conserved.
- Representative mechanisms for coarsening at the late stage of @[email protected] are: (1) material flow in domains driven by @[email protected] (observed in a co-continuous @[email protected]), (2) the growth of domain size by @[email protected] from smaller droplets and condensation into larger droplets, and (3) coalescence (fusion) of more than two droplets. The mechanisms are usually called (1) Siggia s mechanism, (2) @[email protected] (or the Lifshitz–Slyozov mechanism), and (3) coalescence.
- @[email protected] coarsening can be substantially stopped by, for example, vitrification, @[email protected], and pinning, the slowing down of molecular @[email protected] across domain interfaces.
