Abstract

Abstract: Microstructure and mechanical properties of Mg–Zn–Y alloy including LPSO phase and I-phase was investigated. Transmission electron microscopy, x-ray diffraction analysis and differential scanning calorimeter analysis reveal that the LPSO (long period stacking ordered structure) phase and I-phase can co-exist within the α -Mg matrix. Wherein, the quasicrystal phases exist in the (I-phase + α -Mg) eutectic structures. In the Mg–Zn–Y alloy, it is also found that 14 H type LPSO phases consist of LPSO phase and I-phase. With the addition of quasicrystal master alloy content, the microstructures are refined, and the mechanical properties are enhanced.
