STRESS-CORROSION STUDIES OF ALUMINUM ALLOY 7079-T6 IN SEAWATER,

Abstract

The stress-corrosion susceptibility of Aluminum Alloy 7079 in the T6 temper was investigated as a function of longitudinal, long-transverse, and short-transverse plate orientations. The alloy was found to be susceptible to stress-corrosion and pitting attack. Specimens oriented in the short transverse direction had the lowest resistance to damage in seawater. Variations in orientation-dependent stress-corrosion cracking susceptibility were related to microstructural characteristics. The alloy is considered unsuitable for naval applications under conditions conducive to stress corrosion. (Author)
