AbstractStress corrosion crack growth rates of alloy 690 thermally treated (TT) after one-directionally (1D) cold-rolling along the longitudinal (L) direction and three-directionally (3D) cold-rolling were successfully measured by ACPD technique in deoxygenated water with different dissolved hydrogen contents (C(dH)) at 340 degrees C. The fracture mode is mainly intergranular mode in both two kinds of alloy 690TT. The crack growth rates in the T-L orientation are higher than those in the L-T orientation in 340 degrees C deoxygenated environments. For 1D 25% alloy 690TT with T-L orientation, the measured average crack growth rate is 4.8x10(-11) m/s in 340 degrees C water with C(dH) 30 mu L/g, and the measured average crack growth rate is 1.1 x10(-10) m/s in 340 degrees C water with C(dH) 10 mu L/g. The mechanism of crack growth is internal oxidation mechanism.
