Abstract
Electrical resistivity measurements were employed to follow the annealing of point defects during isochronal and isothermal ageing and reversion in quenched Al-1 to 4.4 Zn, Al-1 to 4.4 Zn- 0.01 to 0.3Be and Al-4.4Zn-0.01 Fe, Mn and Si alloys. Quenched-in resistivity, initial ageing rate and time-to-peak during ageing were experimentally measured as a function of quenching and ageing temperatures to determine the apparent vacancy formation and migration energies in the various alloys. Results were used to evaluate solute-vacancy (s-v) binding energies and alloy decomposition modes and to propose a model for the decomposition of quenched binary alloys containing ternary trace additions.
