Mg-Zn-Y alloy system has been a great interest in Mg alloys strengthened by the stable icosahedral quasicrystal phase (I-phase). The strengthening mechanism with increasing of the volume fraction of I-phase can be explained by dispersion hardening due to the dispersion of I-phase particles. Therefore, the purpose of this work was to study the hot compressive deformation behavior of the cast Mg-Zn-Y alloys containing different volume fraction of I-phase. The Mg99.3Zn0.6Y0.1, Mg97.9Zn1.8Y0.3 and Mg93.7Zn5.4Y0.9 alloys were prepared by casting into steel mold and homogenized. Hot compression test were performed in the Gleeble machine at temperature range of 200-400 ℃ with strain rates range of 0.001-10/s. OM, SEM, and EBSD were used to analyze the microstructure and texture.
