| description | To lay theoretical foundations for room and elevated temperature application of AZ91 magnesium alloys, microstructure and mechanical properties of AZ91 magnesium alloys strengthened by Mg-based spherical quasicrystalline phase have been investigated using XRD, SEM, TEM, hard-meter and impact testing machine. The experiment results show that macro-hardness and impact toughness of AZ91 magnesium alloys were improved a lot as the addition level of spherical quasicrystal containing Mg–Zn–Y–Mn master alloy increased; while adding 5.1wt.% spherical quasicrystal containing master alloy, impact toughness of AZ91 matrix composites reached the peak value, 15.3Jcm−2, which was about 252% as many as that of AZ91 master alloy. Majority of β-Mg17Al12 phase dissolved when spherical quasicrystal particles remained stable after 28-h T4 solution treating. Small dimples on fracture surface by impact of AZ91 magnesium alloy strengthened by quasicrystal particles exhibited the feature of ductile fracture. |
