The addition of Ag significantly increases the early ageing response, overall ageing response and peak age-hardening of an Al-Zn-Mg-Cu alloy. Ag is the most segregated of the solutes during ageing and a positive correlation between Ag and Cu exists in clusters and larger aggregates throughout the precipitation sequence (1-120 min).
