Stress corrosion cracking (SCC) susceptibility of A1-Zn-Mg-Cu-Zr base 7010 alloy of two different tempers viz. T6 (peak aged- two step aging) and T73 (over aged- three step aging) have been investigated in air and an aqueous environment (non-deaerated 3.5 wt.% NaCl solution) by slow strain rate testing (SSRT) as well as U-bend testing. The tests have been carried out at ...
