Abstract

The temperature-induced liquid-liquid structural transition has been observed and testified in different kinds of alloys. The effect of liquid-liquid transition on the morphology of solid/liquid interface was investigated by means of the unsteady-state unidirectional solidification. The results showed that the interface instability of Sn-1wt.%Pb was developed after the liquid structural change, which suggested that the solute distribution coefficient decreased due to the structural change of liquid Sn-1wt.%Pb and the solute on the frontier of solid/liquid interface enriched.
