ժҪ In order to confirm the segregation characteristic of phosphorus in an Fe-17Cr alloy at grain boundary, the phosphorus segregation was obtained by Auger electron spectroscopy. The results show that a maximum phosphorus segregation appeared at 450 �� for all specimens aged for 30 min at 350, 400, 450, 500, and 600 �� after being solution-treated at 1000 �� for 1 h. These results were analyzed by the characteristics of segregation peak temperature of non-equilibrium segregation.
