Which consequence during rapid silicon solidification causes polycrystalline formation?

💡 Explanation

Polycrystalline structures arise when rapid cooling leads to insufficient time for atoms to arrange into a single crystal lattice; metastable phase diagram undercooling occurs because rapid cooling suppresses equilibrium phases rather than allowing uniform crystal growth, therefore forming grain boundaries.
