Effects on the stress corrosion cracking in Al-Mg alloys of the accelerating anodic current, the temperature of solid solution treatment, the anodizing treatment and the addition of some elements were investigated.Between the logarithm of anodic current density and the logarithm of time to failure, a linear relationship was observed, but this was altered by the applied stress. As a result of considering this relationship, it is shown to be necessary to take the mechanochemical reaction into cosideration in the natural stress corrosion, and thus the one-step process mechanism in stress corrosion would not seem to hold in this case.The stress corrosion susceptibility varied with the temperature of solid solution treatment due to changes of the grain size of alloys. The anodizing was not always effective, since the susceptibility of the alloys rather in creased when sharp notchs along grain boundaries were formed during anodizing due to the preferred dissolution of precipitates. Finally, marked effect of Cr addition on the stress corrosion of Al-Mg alloys was observed. A small addition Zr was very effective and Mn was also effective at lower applied stress. Y and Bi were little effective.
