摘要

•TMT studies of 3wt.% Li on Al–0.5Mg–0.2Si in W, T6 and T8 conditions.•Artificial aging at 175°C for 2–12h with prior cold reductions of 10–60%.•Hardness surveys, YS and UTS, microscopy, fractography and DSC studies.•Mechanical properties significantly enhanced in T8 condition.•Property enhancement attributed to a possible refinement of δ′ (Al3Li) precipitates.
