The CuCr alloy was prepared by the SHS electromagnetic casting using CuO and Cr

as materials and Al powder as reducing agent. The effect mechanism of the electromagnetic stirring on the microstructure of CuCr alloy was analyzed. The calculated results show that the cooling process is the fast cooling of Newton Cooling. Electromagnetic stirring can improve the properties of the CuCr alloy by effectively inhibiting the growth of dendrite to refine grain size and homogenize the distribution of Cu and Cr in the alloy. The optimized stirring time is about 7 min because grain can not be effectively refined stirring time in excessively shorter

and in turn

it is easily generated composition segregation

choosing preheated temperature of cast mold for 500 ℃. Although Ni

Co can improve the dispersity and homogeneity of Cu and Cr in the alloy

it can result in coarsening grain size.
