The ageing behavior of an Al-4.6Mg-0.54Cu (in wt.%) alloy was studied after: (i) solutiontreatment for 1h at 530°C, and (ii) annealing at 280°C for 3h. Both groups of the heat treatedspecimens underwent further thermo-mechanical processing: 5% pre-deformation in tension +artificial ageing at various temperatures: 140°, 160° and 180°C for 30 min. Effect of the thermomechanicalprocessing on the microstructure and mechanical properties was investigated by tensiletesting and electrical resistivity measurements.Solutionizing at 530°C resulted in higher resistivity level indicating that the most of soluteatoms are retained in the solid solution. This provides great potential for precipitation hardening ina wide range of ageing temperatures. On the other hand, it appears that most of the main alloyingelements precipitated during the annealing at 280°C thus diminishing the ageing potential. Afterfurther thermo-mechanical processing, the specimens annealed at 280°C showed significantly lowerstr...ength level than once solutionized at 530°C.
