Abstract

The stress corrosion cracking (SCC) behavior of AA 7050-T7451 (UNS A97075) aluminum alloy in 3.5 wt% NaCl solution has been studied using slow strain rate tension technique. The effects of strain rate, solution pH, and dissolved oxygen on SCC behavior has been investigated. The experimental results show that a specimen with short transversal orientation is susceptible to SCC at a strain rate of 8.0 × 10-7 s-1. The SCC resistance of 7050-T7451 alloy decreases with the presence of dissolved oxygen or increasing solution acidity.
