Abstract
Federighi and Passari1 have recently directed attention to the increase in electrical resistivity associated with the early stages, of ageing in binary aluminium alloys in which age-hardening involves pre-precipitation effects such as the formation of Guinier–Preston zones. Recent work in this Establishment has shown that this effect occurs in more complex ternary and quaternary aluminium alloys and is particularly marked in the Al–Zn–Mg–Cu system.
