Stress corrosion cracking of an age-hardened Al-Zn-Mg alloy (7039) subject to continuous immersion in a 1 N NaCl solution was studied at stresses of 5 to 55 ksi and temperatures of 30 to 100 C and found to be an activated process. The rate, r, of stress corrosion (proportional to the inverse failure time) can be expressed as:
aluminum alloy, stress corrosion, cracking, activation, electrochemical dissolution, pitting (corrosion), corrosion
