The transient creep of Al‐16 wt% Ag and Al‐16 wt% Ag‐0.1 wt% Zr solid solution alloys is investigated in the temperature range 428 to 673 K for various ageing times under constant load. The subsequent decrease and increase in the values of creep parameters n and β with increasing ageing times and ageing temperatures has been explained on the basis of structure transformations occuring in Al‐Ag alloys. It was found that the addition of Zr to Al‐16 wt% Ag alloy accelerates the precipitation of GP zones, γ′‐phase, and γ‐phase. TEM investigations confirmed the above effects. The mean values of the activation energy of both alloys were found to be equal to that quoted for dislocation intersection.
