Influence of Low Frequency Electromagnetic Field on the As-Cast Structure of Cu-10%Sn-2%Zn Alloys

Abstract:

In this paper, the effect of low frequency electromagnetic field on the as-cast structure of Cu-10%Sn-2%Zn alloys and inverse segregation of Sn had been investigated. It is found that macrostructure and δ phase was refined, columnar-to-equiaxed transition was promoted, and inverse segregation of Sn was inhibited by applying electromagnetic field during the solidification of Cu-10%Sn-2%Zn alloys. 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.
