Abstract: Mg-1Si alloy doped with 1%Y was prepared by in-situ reaction synthesis. The effect
of hot extrusion on the microstructure and elevated-temperature mechanical properties of the
alloy was studied. The microstructures were analyzed by optical microscopy, scanning electron
microscopy with energy dispersive X-ray spectroscopy and X-ray diffractometry. The results show
that as-cast Mg-1Si-1Y alloy consists of dendritic α-Mg phase, eutectic needle-like Mg2Si phase
and Mg24+xY5 phase precipitated from α-Mg, Mg2Si can be modified and refined by yttrium, and
α-Mg grains can be refined by dynamic recrystallization occurred in hot extrusion process. The
tensile strength and elongation of the alloy at ambient temperature are improved prominently by
