摘要	Environmentally assisted crack growth in thermally treated Alloy 690 cold worked one-dimensionally to the thickness reduction of 25% in primary water was investigated. In the water at 50 degrees C and dissolved hydrogen (DH) of 2.7-2.9 ppm, the alloy showed a crack growth rate of <2.2 x 10(-9) mm/s at a stress intensity factor of 35 MPa root m. In the water at 340 degrees C, stress corrosion crack growth rate of <1 x 10(-8) mm/s was observed in the alloy over a DH range of 0.37-2.6 ppm. Further, it was found that hydrogen could promote SCC growth when increasing DH from a very low level. (C) 2012 Elsevier Ltd. All rights reserved.
