A new process for combining alloys in the reaction chamber by inmold process was developed to control transitional graphite structure varying from spheroidal to flake and vice versa. Inoculant was placed on the spheroidizer in the chamber basically. Molten iron was treated in one chamber by two different reactions with time-lag. Spheroidized iron melt was dissolved and cast into the cavity immediately after dissolution of the inoculant. Transitional graphite structure varying from flake to spheroidal was formed in the casting from the lower layer to upper due to some properties differences between the two melts. Effects of the combination of both graphitizer and inoculant placed in the chamber on the graphite structure were investigated in this study. The aimed transitional graphite structure was produced in the casting, when the inoculant was placed on the spheroidizer in the chamber at a ratio from 1.0 to 2.5.
