Sustained load and rising displacement tests were performed on precracked specimens to investigate the environmentally assisted cracking (EAC) behavior of AISI 4340, σ0 = 1095 MPA (159 ksi), in flowing synthetic seawater. J-R resistance curves were generated in environment over four orders of magnitude in displacement rate and KIJ (from JIC ) from the slowest test was found to agree closely with the KIEAC (KISCC ) value determined from cantilever beam tests. Crack velocity data from the slowest rising displacement test and constant stroke—decreasing KI —tests fall on the same line suggesting that there is a unique ȧ-KI curve for EAC in this system. A method is suggested to determine the displacement rate needed to obtain a good estimate of KIEAC from a rising displacement test.
