摘要：

Stress corrosion cracking growth rate of uni-directionally cold-rolled 316L stainless steel was monitored in simulated PWR primary water with different dissolved hydrogen (DH) concentrations at 320 degrees C. Crack growth rate at a DH of 0.16 cm(3) (STP) H-2/kg H2O is close to that at 5 cm(3) (STP) H-2/kg H2O. Crack growth rate at 30 cm(3) (STP) H-2/kg H2O is about one fourth of that at 5 cm(3) (STP) H-2/kg H2O or two times of that at 50 cm(3) (STP) H-2/kg H2O. Electron back scattering diffraction results show typical intergranular SCC along high angle boundaries with high levels of deformation. (C) 2011 Elsevier Ltd. All rights reserved.
