Surface-Directed Spinodal Decomposition

Physical Review Letters, 1991
The spinodal decomposition of mixtures of poly(ethylenepropylene) (PEP) and perdeuterated poly-(ethylenepropylene) has been studied near the surface using forward-recoil spectrometry. Instead of the composition waves with randomly oriented wave vectors (and random phases) found in the bulk, we observe composition waves with wave vectors normal to, and ...

Segregation-driven grain boundary spinodal decomposition as a pathway for phase nucleation in a high-entropy alloy

Acta Materialia, 2019
Elemental segregation to grain boundaries (GBs) can induce structural and chemical transitions at GBs along with significant changes in material properties.

Spinodal decomposition in a polymer solution

Physical Review A, 1992
The spinodal decomposition in a critical mixture of polydimethylsiloxane--diethyl carbonate was investigated by a time-resolved light-scattering technique, focusing especially on the early and the intermediate stages of phase separation. The most essential characteristics of this system are that both the refractive index and the density of the solvent ...

Spinodal decomposition of a crystal surface

Physical Review A, 1992
A phenomenological equation of motion for an unstable planar crystalline interface is derived and used to describe the early stages of hill and valley formation. We calculate the critical wave number for the growth of instabilities and the scattering structure function.

On spinodal decomposition

Acta Metallurgica, 1961
Abstract The stability of a solid solution to all infinitesimal composition fluctuations is considered, taking surface tension and elastic energy into account. 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 ...

Spinodal decomposition in a binary fluid

Physical Review Letters, 1993
Light scattering has been used to study a mixture of 3-methylpentane and nitroethane undergoing spinodal decomposition. The scattered intensity has been measured in absolute units allowing the first test or theory with no adjustable parameters. The measured structure factor does not evolve according to theory even when the initial fluctuations are ...

Phase field simulation of spinodal decomposition in Zr–Nb alloys for implant materials

Journal of Applied Physics, 2019
Zirconium (Zr)-based alloys, a new class of hard-tissue replacement materials, show lower strength compared to traditional medical metal materials such as stainless steel, cobalt alloy, and Ti-6Al-4V alloys, which may lead to premature fracture of the ...

Spinodal decomposition in 3-space

Physical Review E, 1993
Using a cell-dynamical system (CDS) to model the separation of phases, we present the results of large-scale simulations of spinodal decomposition in 3-space of a symmetric binary alloy and incompressible binary fluid at critical quench. Our main results are (1) the reliable determination of the asymptotic or the almost asymptotic form factors for ...
