Enrichment of massive graphite on lateral surface and evident macrosegregation along both longitudinal and axial directions were found by the influence of intense electromag- netic stirring during unidirectionally solidifying grey cast iron ingot.A secondary flow within the region near solidliquid interface seems to be the cause of axial segregation, and the solidification rate may also be influential in the macrosegregation.
