%X Studies were made of the influence of aging conditions and applied potentials on the stress corrosion cracking (SCC) susceptibility, for an Al-Li-Cu-Mg alloy by slow strain rate technique. The relationship between the relative hydrogen content on specimen surface and the applied potentials and elapsed time has also been examined. The SCC susceptibility was found to be dependent on aging conditions in which the peak aged condition gave the worst SCC resistance and the natural aged condition had the best one. The SCC susceptibility and sur- face hydrogen content are related to the applied potentials. The anodic potentials increase SCC susceptibility, while the cathodic ones below the critical accelerate SCC. It is considered that both the anodic dissolution and hydrogen embrittlement contribute to SCC.
