Stress corrosion cracking of a 7079-T6 aluminum alloy in seawater was investigated by bend tests of smooth and precracked specimens. It was found that there was a general agreement between results of the two methods. The susceptibility of this alloy to inter-granular cracking was shown to depend on its directional characteristics. The use of precracked specimens for stress corrosion testing is discussed.

6082 Al Alloy

In this work, the effect of pH (3, 7 and 10) on the stress corrosion cracking behavior of 6082 aluminum alloy, in a 0.3 M sodium chloride (NaCl) aqueous based solution was investigated. The stress corrosion cracking behavior was studied with slow strain rate testing, whereas failure analysis of the fractured surfaces was used to identify the dominant degradation mechanisms. The experimental results clearly indicated that stress corrosion cracking behavior of this aluminum alloy strongly depends on the pH of the solution. In particular, the highest drop in ultimate tensile strength and ductility was observed for the alkaline pH, followed by the acidic, whereas the lowest susceptibility was observed in the neutral pH environment. This observation is attributed to a change in the dominant stress corrosion cracking mechanisms.
