An Al – 5Zn – 1Mg alloy was aged at three different temperatures, 70°C, 150°C, and 200°C to obtain different states of precipitation. Serrated flow behaviour was studied with progressive aging at these three different aging temperatures. A comparison of serrated flow behaviour for the three different aging condition was made in the peak aged condition. Finally, serrated flow behaviour in Al – 5Zn – 1Mg alloy was compared with that in Al – Li alloys studied earlier. It is concluded that all the features of serrated flow can be explained only by considering the combined effect of solute – dislocation and precipitate – dislocation interaction.
