Microstructure Evolution of Hypereutectic Cu₉₈Cr₂ Alloys

Abstract:

Hypereutectic Cu₉₈Cr₂ alloys were prepared by vacuum arc melting and electromagnetic levitationing method. The microstructure evolution was investigated during the solidification process. It is shown that for the arc melted hypereutectic Cu₉₈Cr₂ alloy, the general microstructures consist of primary β(Cr) grains distributes on α(Cu) matrix and (α+β) eutectics set in cellular α (Cu) phase. However, due to the different solidification rate, the primary β(Cr) phase, (α+β) eutectics and α(Cu) phase coexist for the electromagnetic levitated hypereutectic Cu₉₈Cr₂ alloy. The reason for the different microstructure and evolution for the hypereutectic Cu₉₈Cr₂ alloy is studied in this paper.
