Neutron Irradiation--Induced Phosphorus Segregation in Reactor Pressure Vessel Steels
中子辐照诱导压力容器钢中磷的偏析

Neutron irradiation-induced phosphorus intergranular segregation in the reactor pressure vessel steels is the one of main reasons resulting in brittle fracture of the nuclear reactor vessel. In this paper, a solute drag model was proposed to predict the phosphorus inter granular segregation in reactor pressure vessel steels and compared with the rate theory model. The predicted results show a good agreement with experimental data recently published for pressure vessel steels (C-Mn and MnMoNi steels).
