Abstract

In hyper-eutectic Al–Si alloys fabricated by 4–N aluminum and 5–N silicon, the morphology of primary silicon crystals at constant temperature of the solid-liquid co-existent temperature region was investigated. Supersaturated, non crystallization of silicon, alloy made by rapid solidification process were re-melted at the solid-liquid co-existent temperature region. The primary silicon was crystallized to the blocky shape. In the case of quenching by the solid-liquid temperature region after the melting, the primary silicon crystals grew to the petal shape. These crystallizations grew with same shape during isothermal holding at the solid-liquid co-existent temperature region. The primary silicon grew that the ration of length/width was reduced slightly, in the case of continuous cooling.
