Abstract
Irradiation-induced impurity segregation to grain boundaries is one of the important radiation effects on materials. For this reason, phosphorus segregation to prior austenite grain boundaries in a P-doped 2.25Cr1Mo steel subjected to neutron irradiation is examined using field emission gun scanning transmission electron microscopy (FEGSTEM) with energy dispersive X-ray microanalysis (EDX). The steel samples are irradiated around 270 and 400degreesC, respectively. The irradiation dose rate and dose are similar to1.05x10(-8) dpa/s and similar to0.042 dpa respectively for 270degreesC irradiation, and 1.7x10(-8) dpa/s and 0.13 dpa respectively for 400degreesC irradiation. The FEGSTEM results indicate that there is no apparent phosphorus segregation during 270degreesC irradiation but there is some during 400degreesC irradiation.
