| Abstract Scope |
Phase field (PF) methods have been successfully applied to study spinodal decomposition occurring near thermodynamic equilibrium. This approach has recently been extended in a unified framework to study the nucleation and growth process. Although much work has been done over the past thirty years to model radiation-induced microstructures in this framework, the validity of extending this approach to far from equilibrium remains uncertain. In this work, we discuss the validity of such an extension and present comparisons between PF simulations and experimental results obtained from Atom Probe Tomography measurements on FeCr samples irradiated with ions, a classic example of a microstructure far from equilibrium. |
