Effect of liquid structural transition on the morphology of solid/liquid interface during the unsteady-state unidirectional solidification

摘要：

　　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-lwt.%Pb was developed after the liquid structural change,which suggested that the solute distribution coefficient decreased due to the structural change of liquid Sn-lwt.%Pb and the solute on the frontier of solid/liquid interface enriched.
