Two-Step Solid-Solid Transition

Caption

Researchers found that some crystals have an easier time of making solid-solid transitions if they take it in two steps. Surprisingly, the first step of the process involves the parent phase producing droplets of liquid. The liquid droplets then evolve into the daughter phase. In this series of color-coded images, the square-pattern crystal (labeled green) gives rise to liquid 'droplets' (red), which form triangular crystal (blue).
