The electromagnetic field is interested increasingly for its powerful means to control the solidification process. The solidification microstructure can be effectively controlled by the transfer processes with electromagnetic field during solidification. Based on the interaction of the pulsed magnetic field and metallic melt, for example, the as-cast grain size of alloys can be refined to about 50-100 um. The numerical simulation and experimental results show that the pulsed magnetic field causes melt vibration and but melt convection during the solidification of magnesium alloys. By controlling these factors, the nucleation is accelerated at the early solidification stage and a columnar to equiaxed transition occurs during the solidification processing. Magnetic controlled casting technology has been developed by research on intelligent control of solidification structure with the pulse magnetic field.
