The Influence of Solute Depleted Zones on the Stress-Corrosion Susceptibility of Aged Al-7.2 Mass% Mg and Al-4.4 Mass% Cu Alloys

The Influence of Solute Depleted Zones on the Stress-Corrosion Susceptibility of Aged Al-7.2 Mass% Mg and Al-4.4 Mass% Cu Alloys

The influence on stress-corrosion susceptibility of the measured solute de­pleted zone associated with grain boundary precipitation has been studied. The behaviour has been explained in terms of a simple electrochemical model that is consistent with in situ localized grain boundary corrosion potenti...

Zusammenfassung:The influence on stress-corrosion susceptibility of the measured solute de­pleted zone associated with grain boundary precipitation has been studied. The behaviour has been explained in terms of a simple electrochemical model that is consistent with in situ localized grain boundary corrosion potential measurements and explains the kinetics of stress-corrosion crack initiation in these alloys.
