| Abstract: | The development of refining of the primary carbides in high chromium white cast iron is introduced in this paper. The structure and the growth mechanism of the primary carbide and the modification ways are also involved. According to the literatures the morphology of primary carbides is improved significantly with modifying elements such as RE, K, Na, Zn, Mg, V, Ti, B. Suspending casting and alloying are also effective ways of refining of the primary carbides. |
