The main strengthening effect can be attributed to the Q-Al 5Cu 2Mg 8Si 6 and β-type (i.e. Mg 2Si) precipitates due to the fact that the π-Al 8Mg 3FeSi 6 phase is relatively large in size, plate-like in morphology, and low in number density and thereby volume fraction. More importantly, the Zr addition into the Al-Si-Mg-Mn alloys causes the precipitation to start at a lower temperature during ageing, which can be due to the grain refinement effect by Zr addition and thereby enhanced diffusion. This paper provides some insights in precipitation microstructure and thereby shortening the ageing treatment at a relatively low ageing temperature. ",
