Theeffect of Ce on the equilibrium segregation of P and the embrittlement of the alloyshas also been studied in detail. The results show that there is cosegregation of Ceand P at the grain boundaries in Fe-0.3%P-0.16%Ce alloy. The addition of Ce doesnot decrease the equilibrium segregation of P, but significantly lowers the ductile-brittle transition temperature. The interaction between Ce and P at grain bounda-ries was discussed from the point of the interfacial two-dimensional phase.
