Phase field modelling of precipitate morphologies in systems with tetragonal interfacial free energy anisotropy
Arijit Roy, M P Gururajan
A wide variety of morphologies arise due to the tetragonal anisotropy in interfacial free energy. In this paper, we report on a family of Extended Cahn-Hilliard (ECH) models for in…

Phase field modelling of interfacial anisotropy driven faceting of precipitates
Arijit Roy, E S Nani, Arka Lahiri +1
We use extended Cahn-Hilliard (ECH) equations to study faceted precipitate morphologies; specifically, we obtain four sided precipitates (in 2-D) and dodecahedron (in 3-D) in a sys…
