| Abstract |
Metastable liquid phase separation(MLPS) in Cu-Fe binary system was investigated using an electromagnetic levitation technique. The temperature of the MLPS(Tsep) was measured directly from the time-temperature profile during cooling in the levitated state. The metastable liquid miscibility boundary of Cu-Fe binary system was illustrated using these measured Tsep. In Fe-rich alloys, phase separation generally appeared as dispersed L2(Cu-rich) droplets in a L1(Fe-rich) matrix, whereas for alloys containing Fe less than 53 wt%, L1 droplets formed in a L2 matrix. Secondary MLPS was occured in the primary separated L1 droplets by increasing the cooling rate during phase separation. |
