AbstractAbstract
[en] This report summarizes work performed by Argonne National Laboratory on environmentally assisted cracking in light water reactors during the six months from October 1987 through March 1988. The stress corrosion cracking (SCC) of Types 304, 316NG, 347, and CF3M cast stainless steels (SSs) was investigated by means of slow-strain-rate, crevice-bent-beam, and fracture-mechanics crack-growth-rate tests in high-temperature water. The effects of temperature and water chemistry on the crack growth behavior of Type 136NG and sensitized Type 304 SS were determined in long-term fracture-mechanics tests. The influence of dissolved copper and organic impurities on the SCC of sensitized Type 304 SS was also investigated. Fatigue tests are being conducted on Type 316NG SS in air at room temperature to provide baseline data for comparison with results that will be obtained in high-temperature water. The investigation of the susceptibility of several heats of different grades of low-alloy ferritic steels to transgranular SCC in slow-strain-rate tests was continued. 8 refs., 21 figs., 10 tabs
