Abstract:

Grain boundary microstructure as well as the pH in a chloride ion solution environment was found to be significant to stress corrosion attack in 7075 aluminum alloys. The influence of these factors on both the initiation and propagation of cracking and the mode of attack in these alloys are described. Microstructural modifications to attain desirable stress corrosion resistance are suggested.
