Abstract

  The effects of molybdenum, tungsten and silicon contents on the formation of M₂C and M₆C eutectic carbides in multi-component white cast iron were investigated. In substitution of M₂C carbide, M₆C carbide in the fish-bone configuration precipitates in cast irons depending on chemical composition, and it is derived that an increase in both the W/Mo value and silicon content promotes the transition of carbide type from M₂C to M₆C. It is also found that when M₆C carbide precipitates in a large scale, M₇C₃ carbide always follows to crystallize even at low carbon content like about 2 mass % in the iron. With respect to the precipitation sequence of eutectic carbides in the cast iron containing MC, M₇C₃ and M₆C carbides, it is proved to take the order of MC, M₆C and M₇C₃.
