The Influence of Hydrogen on the Stress Corrosion Cracking of Low-Strength AL-MG Alloys

Abstract

There is growing evidence for hydrogen uptake in aluminum alloys and its contribution to the crack growth of high-strength aluminum alloys but less evidence for low-strength alloys. This paper summarizes the evidence for hydrogen uptake in a low-strength alloy AA5083 and its contribution to the stress corrosion cracking of this alloy. A key factor is the anodic dissolution of grain boundary b phase (Al3Mg2) and the associated hydrogen reduction that accompanies this dissolution.
