Resumo
The influence of T3, T8 and T851 thermomechanical treatments on the microstructure and corrosion
resistance of the AA2198 was investigated. Differential scanning calorimetry and scanning electron
microscopy were used for microstructural characterisation, whereas electrochemical methods were
employed to analyse the corrosion behaviour of the alloy. The morphology and composition of
constituent particles were similar for the T3 and T8 thermomechanical treatments but varied in the
T851. There was an inverse relation between T1 phase density and corrosion resistance. The T3
treatment with the highest corrosion resistance was the one with the lowest density of T1 phase.
The mechanisms of corrosion varied with the thermomechanical treatments.
