Abstract The segregation of sulphur at iron/graphite interfaces in both grey and nodular ironwas investigated with AES. Sulphur was found to nonequilibratorily segregated at the interfaces ingrey iron, but not in nodular iron. Such different behaviors of segregation, which will exaggeratethe difference of grey and nodular iron in sulphur content at ircn/graphite interfaces, might bederived from the difference of solidification process between the two irons.
