Abstract
The effect of cerium on temper embrittlement of P-doped Mn structural steels has been investigated by measurements of the ductile-brittle tr ansition temperature and observations by AES, SIMS and SEM of the frac ture surfaces of isothermally embrittled steels. It is shown that P ca n bring about the temper embrittlement of Mn structural steels; cerium may reduce the temper embrittlement of the steels and the segregation of cerium to grain boundaries may play an important part in reducing the temper embrittlement of the steels.
