DYNAMIC SEGREGATION OF SULPHUR IN CAST IRON

Abstract

Abstract: The segregation of sulphur at iron/graphite interfaces in both grey and nodular iron was in- vestigated with AES.Sulphur was found to nonequilibratorily segregate at the interfaces in grey iron,but not in nodular iron.Such different behaviors of segregation,which will exagger- ate the difference of grey and nodular iron in sulphur content at iron/graphite interfaces, might be derived from the difference of solidification process between the two irons.

Key words: cast iron, sulphur, iron/graphite interface, dynamic segregation
