Abstract

The purpose of this work is to show that during slow strain rate testing (SSRT), the laboratory air might not be a non-corrosive atmosphere for evaluating the Iscc (stress corrosion cracking susceptibility index) of high strength Al alloys. Instead, it is proposed that glycerin could be effectively used as the non-corrosive atmosphere to find out the correct Iscc. This is demonstrated while examining 7010 Al alloy in the under aged condition.
