Abstract: By means of the low temperature electrolysis with organic electrolyte and the radioautography the distribution of nodulizing agent Ce in cast iron and high purity Fe-C-Si alloy was investigated. The test results Show that the Ce contect in graphite is higher than that in matrix. Alloying Ce content increases with residual Ce content. The Ce in matrix distribtes non-uniformly concentrating in the last solidification zone.

Key words: Ce, 微观分布, 铸铁
