Abstract

The understanding and control of nanoscale precipitation in an Al-1.0 wt-%Mg₂Si-0.5 wt-% Ag alloy during artificial aging is critical for achieving optimum mechanical properties. To achieve this objective, both differential scanning calorimetry (DSC) and high resolution transmission electron microscopy (HRTEM) have been utilised. The non-isothermal DSC thermograms exhibited eight reaction peaks; six are exothermic (precipitation) and two are endothermic (dissolution) reactions. The activation energies associated with the individual precipitates are determined. With the aid of HRTEM, the evolved precipitates have been characterised.
