DYNAMIC SEGREGATION OF SULPHUR IN CAST IRON

摘要

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 ingrey 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.
