    Abstract

    The stress corrosion cracking (SCC) behavior of two metallic materials in sodium chloride containing solutions has been investigated using precracked specimens and a rising displacement test procedure. The tests were evaluated according to linear elastic fracture mechanics, i.e., in terms of KIscc and da/dt versus K, and, in addition, by applying elastic-plastic fracture parameters such as the J-integral and the crack tip opening displacement (CTOD). From the results of these tests conclusions are drawn concerning an accelerated SCC test procedure that might be based on a combination of the rising displacement test on pre-cracked specimens and the conventional slow strain rate test using smooth specimens.
