Inoculation Mechanisms: Part One :: Total Materia Article
Through inoculation, the graphite nucleation and eutectic undercooling of the iron can be controlled and this will be of crucial assistance in giving the iron its required service properties. Grey cast iron with flak graphite precipitates carbon in the form of cementite and graphite during the process of solidifiion.

Inoculation of Cast Iron | Cast Iron | Iron
Inoculation is a means of controlling the structure and properties of cast irons by increa- sing the nuer of nucleation sites available for the growth of graphite flakes in grey irons or graphite nodules in ductile irons.This r educes undercooling during eutectic solidifiion thereby minimizing the risk of forming hard iron carbides or "chill" in the structure, parti- cularly in thin sections.

Method for Preventing Shrinkage of Cast Iron Parts - …
The cold iron has a fast chilling speed, so the effect of solving the shrinkage defects is better, but the pouring temperature and the inoculation conditions are also relatively high. If the gestation is not good or the pouring temperature is too low, the contact with the cold iron is prone to seepage.
