Fast crystallisation process, animation
Animation demonstrating a fast crystallisation process. This simulation starts with a melted solid (blue spheres) and shows how rapid cooling leads to small crystallites. The simulation is based on the Lennard-Jones potential, which describes interactions between neutral atoms or molecules. As the melt cools, small seed crystals, or nuclei, form and grow as more material deposits onto them. Slow cooling allows more time for nucleation and growth, resulting in larger crystals, while rapid cooling limits this time, leading to smaller, fine-grained crystals.
