Dynamic Effects in Spinodal Decomposition

, 1984
We present a preliminary study of wave propagation in elastic media which can undergo spinodal decomposition. Spinodal decomposition is a phase separation process which takes place by non-linear diffusion.

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.

Achieving high strength via solutes co-clustering and solvents redistribution in an ultralightweight BCC magnesium alloy

Materials Research Letters, 2023
The microstructural features of a high-strength body-centered cubic Mg-Li–Al-Ag alloy are investigated and the strengthening mechanisms are discussed. The results show that obvious spinodal decomposition occurs in the alloy.

Quantification of hardening contribution of G-Phase precipitation and spinodal decomposition in aged duplex stainless steel: APT analysis and micro-hardness measurements

Journal of Nuclear Materials, 2019
Ageing of cast duplex stainless steels (DSS) is attributed to the decomposition of the ferrite: spinodal decomposition and precipitation of G-phase particles. This leads to an increase in hardness and a decrease in Charpy toughness.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Atomistic-continuum hybrid analysis of dislocation behavior in spinodally decomposed Fe-Cr alloys

MATEC Web of Conferences, 2017
In this study, we first present the molecular dynamics (MD) simulation of dislocation behavior in a spinodally decomposed Fe-Cr alloy. The MD simulation is used for exploring the nature of the interaction between a dislocation and the spinodal ...

Using the Cahn–Hilliard Theory in Metastable Binary Solutions

ChemEngineering, 2019
A solution may be in one of three states: stable, unstable, or metastable. If the solution is unstable, phase separation is spontaneous and proceeds by spinodal decomposition.
