Abstract
In studies on stress corrosion cracking caused by hydrogen embrittlement of metals, it has been observed that within the high remperature range rhe Armenius activation energy is negative. This is quite unusual Since ther- mall)' activated crack g.'vwth processes are controlled by positive appar- ent activation energy. The unders/auding of this effect is of inleavst to design and maintenance engineers. The study demonstrates, with a syn- thesis method, a physically rigorous and rational kinetics Of thermally activated processes of some aspects ofenvironment assisted crack growth. It is show that the observed crack growth behavior may be described by single barrier kinetics with forwcud and backward activations.
