摘要：

The stress corrosion cracking (SCC) of austenitic stainless steels in hot magnesium chloride solutions is known to be transgranular. Therefore the slip-step-dissolution model is most favorable when explaining the failure mechanism. Constant load and constant extension rate tests (CERT) show that both methods are almost equivalent. Moreover constant extension rate tests in more concentrated magnesium chloride solutions at 135 degree C reveal a small potential range of intergranular stress corrosion cracking more negative than the range of transgranular SCC.
