The study of Al‐Si hypereutectic alloys in the liquid state can be conducted in quenched samples, which allows the identification of microscopic particles known as Si agglomerates that transform into the well known primary Si particles at the liquidus temperature. The understanding of the nature of the Si agglomerates is the key to determine the exact conditions to refine the microstructure and particularly the primary Si from the liquid or semi‐solid states.
