Microstructure evolution of hypereutectic Cu98Cr2 alloys

摘要：

　　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.
