Abstract：
In order to refine Cu-Ag alloy and further improve the properties, Cu-6%Ag alloy was prepared under different electromagnetic stirring parameters. The results show that with the increase of electromagnetic stirring frequency and current, the grain size of the alloy is obviously refined. The primary Cu dendrites are transformed into equiaxed and cellular crystals, and the Ag content in the cellular crystals decrease significantly. Dendritic Cu phase is beneficial to increase the hardness of the alloy, and equiaxed Cu phase is beneficial to increase the conductivity of the alloy.
