The influence of Ce and P on embrittlement transition temperature in manganese steels has been investigated by using impact test,SEM and Auger spectrometer.The results show that the segregation of phosphorus along the austenite grain boundaries causes a rise in the embrittlement transition temperature.Ce doped in the steels can minimise the degree of segregation of phosphorus and raises the impact toughness and,therefore,reduces the embrittlement transition temperature.
