摘要：

The effect of semisolid heat treatment on the microstructures of three chromium white cast irons has been studied. The primary objective was to examine the effect of semisolid heat treatment on the microstructures with specific emphasis on revealing the variations related to the carbide morphology of the selected materials. It is found that graphitization of carbide in a 1(.)5 wt.% chromium cast iron is enhanced during isothermal heat treatment in the semisolid state. The eutectic carbide in high chromium cast irons is fully or partially modified into discrete particles during heat treatment in the semisolid state.
