Effect of Cooling Rate on the Heterogeneity of Grain Boundary η-Phase Precipitates in 7xxx Aluminium Alloys Following Artificial Ageing Open
The mechanical and stress corrosion behaviour of 7xxx aluminium thick-plate alloys are strongly influenced by a dual distribution of η -phase quench -induced and age -induced grain boundary precipitates (Q-GBPs and A-GBPs) that nucleate in…

Direct comparison of the environmentally induced cracking resistance of 2nd and 3rd generation alloys, AA7050-T7651 and AA7085-T7651 Open
AA7050 and AA7010 aluminium alloys in overaged tempers have been a vital material for aerospace applications since their development in the 1970′s. Latest generation materials including AA7085, AA7449 and AA7037 have higher levels of Zn an…

Mechanisms of Environmentally Induced Crack Initiation in Humid Air for New-Generation Al-Zn-Mg-Cu Alloys Open
Recent experience has shown that new-generation 7xxx-series alloys, that have a high Zn content and Zn/Mg ratios, have a greater susceptibility to hydrogen-environmental induced cracking (H-EIC) on exposure to humid air than more establish…

Understanding the environmentally assisted cracking (EAC) initiation and propagation of new generation 7xxx alloys using slow strain rate testing Open
New generation (new-gen) 7xxx series alloys have recently been shown to have higher susceptibility to environmental assisted cracking (EAC) in humid air, compared to AA7050, in T7651 tempers. Hydrogen (H)-EAC fracture features of brittle i…
