Phase selection of undercooled Cu85Cr15 composites was analyzed by using different solidification conditions. The results revealed that the arc melted composites generally have non-uniform Cr-rich dendrites distributes on Cu-rich matrix. Due to strong electromagnetic stirring, uniform Cr-rich dendrites distributes on Cu-rich matrix for electromagnetic levitation melted composites. Both fine Cr-rich dendrites and Cr-rich particles coexisted in Cu-rich matrix for splat quenched composites, which means liquid phase separation occurred for the high cooling rate.

Liquid phase separation occurred in undercooled Fe-Cu alloys when the undercooling of the melt exceeds a critical value. 5at.% of Si was added into Cu50Fe50 alloy to investigate its effect on the liquid phase separation of Fe-Cu alloys in this paper. It indicated that the addition of Si could enhance the liquid-phase separation in Cu50Fe50 alloy. Additionally, with the increase of undercooling, second liquid-separation occurred in Fe-rich liquids, and many globular, tadpole and peanut-like morphology emerged in the Fe-rich region of Fe45Cu50Si5 alloy. Because of the mixing enthalpy of Fe-Si atomic pairs is more negative than that of Cu-Si atomic pairs; so Si is inclined to rich in Fe-rich region.
