     the high chromium cast iron and medium carbon steel bimetal was fabricated by liquid–solid casting in electromagnetic induction field. the interfacial structure and mechanical properties were investigated. the results show that the microstructure is refined obviously and mechanical properties are improved significantly. the electromagnetic stirring can refine effectively the microstructure, and profit the diffusion of elements and obtaining of the desirable microhardness transition. the electromagnetic induction heating is beneficial to achieving metallurgical interface bonding and improving the mechanical property. furthermore, the electromagnetic stirring compels the molten metal to scour continuously the surface of medium carbon steel, resulting in the oxides and impurities being melted or broken away from the surface.
