Tendency of high-strength aluminum alloys to stress corrosion
Stress corrosion tests were conducted on several high-strength aluminum alloys and heat treatment conditions; Al-Zn-Mg and Al-Zn-Mg-Cu alloys were resistant to stress corrosion in solutions of 3% NaCl and in 3% NaCl plus 0.1% HCl; in absence of stress, corrosion centers have rounded pit form; application of tensile stress transforms these into fine cracks, both transcrystallite and intercrystallite; on formation of microcracks, electrode potential of alloys moves in negative direction.
