This study examined the effect of steady magnetic field on the microstructure and mechanical properties of Mg–Zn–Y alloy reinforced by icosahedral quasicrystal phase. Results show that the microstructure of Mg–Zn–Y alloy was further refined as the magnetic field intensity increased. However, the primary α-Mg gradually became coarse over a certain value. No significant effect on the refinement of icosahedral quasicrystal phase was observed. The plane of the alloy treated by steady magnetic field was substituted by the (0002) plane as the primary plane. The plane was intensified gradually as the intensity of the magnetic field increased. The mechanical properties of Mg–Zn–Y alloy also improved with steady magnetic field treatment.
