A major problem confronting attempts to model environmentally assisted crack growth is the uncertainty present in the rates of electrode reactions within a crack. This results partially from the lack of definition of the solution chemistry and electrode potential at a crack tip. This paper addresses the question of how the environment within the occluded region of a crack differs from that of the bulk environment, and more specifically, identifies ...
The stress corrosion cracking (SCC) susceptibilities of Alloys 600 and 690, AISI 316 NG stainless steel (SS), ASTM A508 carbon steel, and a number of compatible weld metals have been evaluated at 288 C in pure water and in pure water containing sulfuric acid additions. The sulfuric acid was added to simulate the effects of a resin release from the demineralizer system of a boiling water reactor (BWR). A combination ...
