Abstract

Quasicrystal and related phase particles were successfully dispersed in wrought-processed Mg–7.6 wt.% Zn–3.9 wt.% Al alloy with homogeneous and fine-grained structures. This rare-earth-free alloy showed high strength and ductility balance, which was superior to that of the well-known quasicrystal phase dispersed in Mg–Zn–RE alloys, with a weak texture and a reduction of mechanical asymmetry in yield strength.
