摘要 Mg基块体非晶合金因其低成本和高比强度而有望成为轻质高强度结构材料,引起人们研究的极大兴趣。通过对Mg基块体非晶合金发展情况的综述研究,尤其是介绍了新成分设计和力学性能改善等方面的研究现况,发现Mg基块体非晶合金的研究主要集中在Mg-Cu基,成分设计以元素替代和合金体系元素优化为主,Mg基非晶合金塑性的改善是当前研究的重点和难点。 The development of Mg-based bulk metallic glasses （BMGs） was summarized, with an emphasis on the composition design and the mechanical properties improvement. Compared with other composition, Mg-Ou based BMGs were wildly studied by researchers. A lot of Mg-Ou based BMGs with diameters as large as 10 to 27 mm have been discovered. The improvement of plasticity is constantly a research focus on Mg-based BMGs.
