Phase change materials (PCMs) can be categorized into nucleation-dominated and growth-dominated materials. For nucleation-dominated materials, many nuclei are formed in a unit volume; these nuclei grow relatively slowly. Critical nuclei formation also occurs continuously during the growth process so that crystals of different sizes are formed (31). For growth-dominated materials, very few critical nuclei are formed after an often relatively long incubation time, but then crystallization occurs by rapid growth. For these materials, the crystals have similar sizes (31).
Depending on the temperature, sometimes the same materials can behave as either nucleation
dominated or growth dominated.
I wander if there is way to simulate this phenomena with phase field method. Keep this for another day.
