The effect of isochronal aging of quenched Al-2 wt. % Ag and Al-5 wt. % Ag on the steady state creep was determined in the temperature range (393-623 K), by measuring the steady strain rate (E,,) for a period of 120 s at a series of temperature values, 20 K apart. For the two alloys, two and three s
Si-0.1 wt% Zr-0.1 wt% Ti alloys were used to trace the effect of Zr and Ti additions on the behaviour of the steady state creep. After solid solution treatment specimens of both alloys were aged at 623, 673, 723 and 773 K and creep tests were performed at room temperature by applying stresses of 60.
