This paper did the research on Interaction mechanism between Ce and P added in high-carbon steel.with the use of QUANTA-400 SEM and EDS, the morphology of Ce-P-O inclusions were observed.By the Ce，O，P，S surface scanning observation of the inclusion, the inclusions were sured to be Ce-P or Ce-P-O compounds.furthermore,Ce-P compounds were irregular spherical , mainly in the grain. Ce-P-O compounds were long strip, mainly along the grain boundaries.
