Abstract

In situ electrical resistivity measurements were employed to follow precipitation and dissolution processes in an Al-Zn-Mg-Cu alloy under non-isothermal conditions (continuous heating and cooling processes). The initial state of the material (i.e. volume fraction of pre-existing precipitates) was varied in order to highlight the competition between the various precipitation reactions. The precipitate formation and dissolution kinetics could be reliably inferred from the evolution of electrical resistivity. The data indicated that the kinetics of η and T precipitation (and dissolution) is much faster than those of the S phase. The electrical resistivity results were further validated using Differential Scanning Calorimetry.
