Towards predictive simulations of spinodal decomposition in Fe-Cr alloys

, 2022
Simulations of spinodal decomposition in an Fe-36 wt%Cr alloy at 773 K are performed by solving the non -linear Cahn-Hilliard equation, and the results are compared with atom probe tomography measurements.

Spinodal decomposition, ordering, and precipitation transformation in CoCrFeNiAl HEAs under GPa pressure

Journal of Materials Research and Technology
Pressure is a critical component of preparation processes regardless of its magnitude, whether it is a few megapascals, such as in metal squeeze casting, or thousands of megapascals, such as in the experimental preparation of amorphous materials ...

Deterministic and Stochastic Dynamics in Spinodal Decomposition of a Binary System

Успехи физики металлов, 2009
A model for diffusion and phase separation, which takes into account hyperbolic relaxation of the solute diffusion flux, is developed. Such a ‘hyperbolic model’ provides analysis of ‘hyperbolic evolution’ of patterns in spinodal decomposition in systems ...

Spinodal decomposition in liquid crystalline materials

, 1991
The theory of phase separation in a liquid crystal by spinodal decomposition is developed. The time evolution of two coupled parameters, the volume concentration (or mole fraction), and the orientational order parameter is calculated.

Some Aspects of Spinodal Decomposition in Spinel Solid Solutions [PDF]

, 1995
Decomposition morphologies of supersaturated spinel solid solutions in the quasi-binary system Co2TiO4-CoAl2O4 at 973 K show all pertinent features of spinodal decomposition. Since the decomposition morphology may not be considered as sufficient evidence

High temperature phase decomposition in TixZryAlzN

AIP Advances, 2014
Through a combination of theoretical and experimental observations we study the high temperature decomposition behavior of c-(TixZryAlzN) alloys. We show that for most concentrations the high formation energy of (ZrAl)N causes a strong tendency for ...

Structural Control Over Bicontinuous Emulsions from Solvent‐Transfer Induced Phase Separation Through Nanoparticle Loading

Advanced Science, EarlyView.
The nanoparticle loading enables effective control over the liquid domain size in bicontinuous interfacially jammed emulsion gels (bijels) produced through solvent‐transfer induced phase separation (STrIPS). The relationship between the nanoparticle loading and domain size profiles in STrIPS bijels is resolved through confocal microscopy and explained ...
