| Abstract: |
| The current research status of stress corrosion theories were summarized, of which the hydrogeninduced cracking theory and anodic dissolution theory could better explain the stress corrosion cracking behavior of high-strength aluminum. According to the three necessary conditions for occurrence of stress corrosion cracking, the influencing mechanism of the metallurgy factors, environmental factors and stress factors on the susceptibility of stress corrosion cracking of high-strength aluminum alloy and the action results were discussed. Meanwhile, the research progress of laboratory simulation acceleration and natural environmental stress corrosion testing methods, existing problems and future research priorities were introduced. |
