文摘The chemical state of grain boundary cosegregation of Ce and P in Fe-P-Ce alloy system was studied by means of Auger Electron Spectroscopy(AES).The Auger peaks of Ce segregated at grain boundaries are found within the range of 60~180 eV.By comparing with the Auger spectra of the Fe-Ce-P intermetallic compound, it is supposed that there is a two-dimensional interfacial phase at grain boundaries with Ce and P cosegregation which is similar to the structure of the Fe-Ce-P compound.
