Abstract Scope The ductility of Al-Mg-Si-Mn-Fe extrusion alloys is an important property which affects the forming of automotive parts and the in-service behaviour. The precipitation of Mg-Si particles on the grain boundaries during quenching and artificial aging can reduce the fracture strain of the material due to i) strain localization at the grain boundary associated with the formation of a precipitate free zone at the grain boundary, and ii) reduction of the cohesive strength of the grain boundary. The effect of quench rate and aging treatment on strain distribution within the grains and across the grain boundaries has been quantified using high resolution digital image correlation. The results show the degree of strain localization at the grain boundary is dependent on the cooling rate after the solution treatment. The localization correlates with the width of the precipitate free zone and the cohesive strength relates to the precipitate density on grain boundaries.
