摘要：

Segregation of solute atoms such as P to grain boundaries (GBs) in reactor pressure vessel steels can cause intergranular embrittlement. We study the segregation kinetics at low temperatures, where the thermal effects are negligible and the solute atoms are fully adhesive to GBs. An analytical dependence of the GB coverage of segregant atoms on the irradiation dose is derived.
