More Information
Summary:he effect of stress intensity and temperature on the stress corrosion crack growth rates of a 7XXX [AlZnMg(Cu)] and a 2XXX (AlCu) aluminium alloy was measured in water and aqueous salt solutions. Several models of stress corrosion cracking were taken from the literature and are reviewed briefly. These models are based on anodic dissolution, hydrogen embrittlement or enhanced surface mobility. The experimental data are compared with the predicted crack growth rates with the aim of discriminating between the rate-controlling processes of stress corrosion cracking for aluminium alloys in aqueous solutions.
