This study proposed a constitutive equation to predict the change in yield strength according to the behavior of β″ metastable precipitates, which have a profound effect on strength among materials precipitated during the T6 heat treatment of Al-Mg-Si alloy. The β″ precipitate is a metastable phase before it becomes a..... More

DOI: https://doi.org/10.3365/KJMM.2017.55.12.853

The effect of pre-aging treatment on the microstructure and mechanical properties of Al-0.6Mg-1.2Si aluminum alloy sheets fabricated by twin roll casting (TRC) was investigated. It was observed that two kinds of nanoclusters, cluster(1) and cluster(2), play an important role in the bake-hardening properties of Al-Mg-Si aluminum alloy. The hardness of..... More
