The dependence of nodularization of graphite upon Ce content in RE bearing nodular cast iron,prepared by directional solidification,has been investigated by electrolytic extraction-radioisotope assay analysis of Ce in each phase of the iron together with measurement of nodulized graphite.Results show that the Ce occurs mainly as alloyed form. In the graphite phase,the Ce content is believed to be characterization of nodularization.The graphite would completely nodulized only the Ce is over a certain content in graphite phase.
