Abstract： Magnesium alloys possess lots of unique advantages as one of the most promising materials. However, relatively poor mechanical properties limit the application of Mg alloys. As a relatively excellent strengthing phase, icosahedral quasicrystal phase(I-phase) has great influence on Mg-Zn-Y-(Zr) alloys. The yield strength of Mg-Zn-Y-(Zr) alloys could reach 150-450 MPa at room temperature with different I-phase volume fractions, therefore the formation of I-phase has been regared as an effective method to improve the performance of Mg alloys. In this review paper, a series of researches about the Mg-Zn-Y-(Zr) alloys containing I-phase have been discussed, mainly including the current understandings about formation mechanism and I-phase structure, its orientation relationship with a-Mg matrix, and the effect of I-phase on Mg-Zn-Y-(Zr) alloys.
Key words： quasicrystal phase; Mg-Zn-Y-(Zr) alloys; microstructure; mechanical properties

摘要:镁合金拥有许多独特优点， 被认为是最具有应用前景的材料之一。 然而， 力学性能相对较低限制了镁合金的应用。 二十面体准晶相作为一种相对优良的镁合金增强相， 对Mg-Zn-Y-(Zr)合金性能有很大的影响。 通过改变准晶相的体积分数， Mg-Zn-Y-（Zr）合金在室温下的的屈服强度可达到150-450 MPa， 因而生成准晶相被视为一种改善镁合金性能的有效方法。 本文讨论了一系列含有准晶的Mg-Zn-Y-(Zr)合金， 包括准晶相的形成机理、 准晶相的结构和其与镁基体的位向关系， 以及准晶相对镁合金性能的影响。
