摘要：

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. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
