| Abstract: | This paper studies the effect of the C content on microstructure and properties of nanosize cemented carbide. By comparison of physical and mechanical properties of the alloys containing different C content, it is concluded that the C content makes a great difference on the grain size, the microstructure of phase and mechanical properties. This indicates that the growth of grain can be restrained by controlling the C content. |

| Keywords: | the C content nanosize cemented carbide the growth of crystal grain |
