Effect of Electromagnetic Field on the Solidification Structure of C70250 Copper Alloy
The effect of electromagnetic field on the solidification structure of C70250 copper alloy (Cu-3.2%Ni-0.8%Si in mass%) had been investigated in this paper. The results show that applying electromagnetic field during the solidification of C70250 copper alloy can refine as-cast structure and δ-Ni2Si phase. The morphology of δ-Ni2Si phase changes from coarse massive shape to fine dotlike shape. The above-mentioned effects become more obvious with the increasing in current intensity.
