The effect of solution heat-treatment temperature on the undissolved phases was determined for a recrystallized aluminium alloy 2020. The lower solution heat-treatment temperatures retained a greater volume fraction of undissolved TB, T1 and T2 phases, however, these phases did not significantly affect ductility of the alloy. The optimum solution heat-treatment condition (for 10 mm thick plate) in a salt bath was within a temperature range between 505 and 520° C for 30 min. The fracture mode of tensile samples was a form of brittle intergranular fracture regardless of solution heat-treatment temperature.
