Effect of high magnetic field on solidification microstructure evolution of a Cu-Fe immiscible alloy

Abstract

Immiscible alloy, also known as liquid phase separation alloy, has been of increasing interest in recent years. Many immiscible alloys have special physical and mechanical properties [1][2][3][4] . For instance, liquid immiscible alloys like Cu-Pb and Al-Pb alloys with high thermal conductivity and low friction coefficient can be used as advanced bearing materials [5] , and Cu-Co system alloys are excellent magneto-resistive materials [6] .Liquid phase separation is an important phenomenon for immiscible alloys. During the solidification process, when the alloy cools to the critical temperature, the melt immediately enters the immiscible zone and undergoes a phase transformation in which the parent phase L decomposes into two liquid phases, L 1 and L 2 , with different compositions and densities. Finally, the liquid
