| Abstract: | The composite cast experiment of the cemented carbide cast iron had been presented in this paper.The connection mechanism of cast iron cemented carbide was studied by analyzing the morphology of microstructure and the constitutive elements in the transition zone.It was showed that The metallurgical connection was formed because of the diffusion reaction,interface reaction and formation of the new compounds during the composite casting. |
