Cahn-Hilliard systems serve as models for several phase separation phenomena in metal alloys. In this talk, I will talk about the dynamical aspects of a certain type of phase separation - known as nucleation - in which the material separates into small droplets. I will present numerical studies in the context of alloys consisting of three metallic components. The numerics give a statistical classification for the distribution of droplet types as the component structure of the alloy is varied. We relate these statistics to the low-energy equilibria of the deterministic equation computing numerical bifurcation methods.
