James, L A

Fatigue-crack propagation (FCP) tests were conducted on specimens of cast ASTM A27 steel in simulated Hanford ground-water at 150/sup 0/C and 250C/sup 0/C. Fatigue loadings were employed as the most feasible means of accelerating the environmentally assisted cracking (EAC) process. A tentative threshold for EAC was established, and an example calculation was used to show how such a threshold can be related to allowable stress levels and flaw sizes to assure that EAC will not occur.
