Stress and strain-induced corrosion processes

Metallic materials are damaged during operational application if the given application limits are exceeded regarding mechanical, thermal and corrosive stressing. These limiting values of influencing parameters for the constructive design and continuous operation are of interest which when exceeded result in corrosion damage. The greatest part of corrosion damage occuring from operation can be traced back to the combined effect of electrochemical corrosion attack and mechanical-physical stresses where one or the other component may overrule. The most important corrosion damage resulting from the combined effect of mechanical and corrosive stressing are stress corrosion and vibrational crack corrosion. (orig.)
