Article Preview

The effect of electromagnetic field on the solidification structure of C90500 tin bronze (Cu-10%Sn-2%Zn in mass%) had been investigated in this paper. The results show that applying electromagnetic field during the solidification of C90500 tin bronze can refine macrostructure and δ phase, promote columnar-to-equiaxed transition, inhibit inverse segregation of Sn, and make the dendrite degenerate. The width of eutectoid structure (α-Cu+δ) becomes smaller, and the morphology of eutectoid δ changes from coarse acicular and massive shape to fine dotlike shape. The above mentioned effects become more obvious with the increasing of current intensity.
