摘　　要：相对于晶态镁合金,镁基金属玻璃因其高强度、耐腐蚀性等特性,近年来引起了人们的普遍关注。然而它较低的玻璃形成能力及室温脆性却是其走向工业应用的瓶颈,因此该领域的研究主要集中于通过成分设计、添加第二相等方法来提高其玻璃形成能力和塑性。综述了其最新研究进展并提出了当前的研究重点。Mg-based metallic glasses,which attract many attentions currently,possess higher strengths,better corrosion-resisting and so on than its crystalline counterparts. However, the low glass forming ability and ductility at room temperature are bottleneck to industry application. So the researches in this field focused on improving the glassforming ability and ductility of Mg-based metallic glasses by changing composition or adding second phases are summarized. Research emphases as well as developing trend of this field are also mentioned in this paper.
