Results of slow strain rate testing of the Al-Zn-Mg and Al-Zn-Cu-Mg aluminium alloys in NaCl solutions are presented. The evidence of hydrogen contribution to stress corrosion cracking is demonstrated by the effects of addition of arsenic trioxide, post exposure storage and cathodic polarisation on susceptibility to stress corrosion cracking. The mechanism of hydrogen-assisted stress corrosion cracking that includes the concept of critical hydrogen concentration dependent on grain boundary microstructure is discussed.
