Abstract A fractographic study on 10MnP and 15MnP steels with or without RE additions,as well as on Iron-phosphorus alloys under normalized or annealed and then reheated at 700℃ W. C. conditions has been carried out by SEM. The electrode potentials on fracture or polished surface of the RE free steels have been determined, and further investigations on their fractures have also been made by AES and ion-probe analysis.It was found that no intergranular fracture occurs in all the specimens ruptured at room temperature till—100℃. Most of the fractures are brittle cleavage in nature, except that a little ductile fracture appeared on fractures of the specimens ruptured at the interval from room temperature to—25℃. It seems that the cleavage fractures are enriched with phosphorus.
