Abstract
The resistivity has been used to study the early stages of natural ageing in a commercial aluminum alloy. The ageing curves are simple exponentials, the temperature-dependent parameter characterizing the temperature dependence of the process and agreeing with the activation energies for low-temperature ageing of binary aluminum alloys. This suggests that ageing is due to quenching vacancies.
An initial fall in resistivity is interpreted as resulting from some process, additional to zone formation. The nature of this process is discussed.
