Recrystallization kinetics were studied in several AA1200-type samples with different concentrations of iron, silicon and titanium. The samples included commercial AA 1200 and several laboratory cast materials, Al-0.5%Fe, Al-0.5%Fe-0.1%Si and Al-0.5%Fe-0.1%Si-0.02%Ti. The samples were cold-rolled 90% and annealed at different temperatures. For each sample the softening curves were produced using tensile test data. Thermoelectric power and resistivity measurements were used for estimating the concentration of elements in solid solution. It was found that the softening temperature rose rapidly as the amount of solute iron increased up to 0.003%. A further increase in solute iron from 0.003% to 0.025% resulted only in a marginal change in the softening temperature. Titanium and silicon in solution had a rather small effect on the recrystallization kinetics.
