Liquid-Liquid Structure Transition and its Effects on Solidification Behavior of Binary Alloys

Article Preview

Abstract:

In our work, some anomalous changes, namely the temperature-induced liquid-liquid structure transitions, were observed at the temperature hundreds degrees above the corresponding liquidus in some binary alloys. Based on the results of liquid structure transitions, corresponding solidification experiments have been carried out on the alloys melted and held at the temperature above or under the liquid-liquid structure transition (L-LST), respectively. It is found that L-LST has a significant effect on solidification behavior and microstructure. There is a general rule that the super-cooling degree increases and the microstructure becomes finer cast from the liquid experienced L-LST.
