In this study, we investigated the effect of aging treatment at 573 K on hardness in Mg-Sc alloy with bcc/hcp dual phase prepared by annealing at 873 K. It was found that hardness abruptly increased after some incubation time, and then reached steady state level. Moreover, by further aging, the hardness increased again. It was confirmed by SEM observation and XRD that the initial drastic hardening was due to the precipitation of α phase. Furthermore, XRD results suggested that the secondary hardening was attributed to the formation of MgSc phase with ordered B2 structure.
