Three-dimensional phase-field simulations of directional solidification
M. Dejmek, R. Folch, A. Parisi +1
The phase-field method has become in recent years the method of choice for simulating microstructural pattern formation during solidification. One of its main advantages is that ti…
Phase-field Modeling of Eutectic Solidification: From Oscillations to Invasion
R. Folch, M. Plapp
We develop a phase-field model of eutectic growth that uses three phase fields, admits strictly binary interfaces as stable solutions, and has a smooth free energy functional. We u…
Linking Phase-Field and Atomistic Simulations to Model Dendritic Solidification in Highly Undercooled Melts
Jean Bragard, Alain Karma, Youngyih H. Lee +1
Even though our theoretical understanding of dendritic solidification is relatively well developed, our current ability to model this process quantitatively remains extremely limit…
Spinodal decomposition of an ABv model alloy: Patterns at unstable surfaces
Mathis Plapp, Jean-Francois Gouyet
We develop mean-field kinetic equations for a lattice gas model of a binary alloy with vacancies (ABv model) in which diffusion takes place by a vacancy mechanism. These equations…
