Part of my research has been focused on mathematical models for phase separation
in multi-component alloys, in particular on the phenomenon of nucleation.
Below you can see some movies of simulated phase separation in a ternary
Cahn-Morral model with components U, V, and W, for a variety of values of
the total mass m_{U}. The remaining two components have masses
m_{V} = 0.2 - m_{U} and m_{W} = 0.8.

m_{U} = 0.100 | m_{U} = 0.105 | m_{U} = 0.110 |

m_{U} = 0.115 | m_{U} = 0.120 | m_{U} = 0.125 |

m_{U} = 0.130 | m_{U} = 0.135 | m_{U} = 0.140 |

The following simulations are for the same mass values, but for larger interaction length. They show the formation of the nuclei more clearly.

m_{U} = 0.100 | m_{U} = 0.105 | m_{U} = 0.110 |

m_{U} = 0.115 | m_{U} = 0.120 | m_{U} = 0.125 |

m_{U} = 0.130 | m_{U} = 0.135 | m_{U} = 0.140 |
