Environmentally Assisted Cracking Behavior of a High-Level Nuclear Waste Container Alloy


The environmentally assisted cracking behavior of cast ASTM A27 steel in a simulated groundwater environment was studied using both statically loaded and cyclically loaded specimens. The results show that, compared to other aqueous environments, the groundwater environment is relatively nonaggressive. The nonaggressive nature of this environment is believed to be related to its high pH and low level of dissolved oxygen.
