摘要
Al基金属玻璃具有高强度、高韧性、良好的耐蚀性,特别是其比强度高达330kN·m/kg,作为新结构材料在航空航天领域具有潜在的应用前景。近年不仅研发出了具有大过冷液相区以及能形成块体金属玻璃的Al基合金,还通过粉体温热固化成形工艺实现了Al基金属玻璃的大块体化,推动了其在实际生产中的应用。简述了有关Al基金属玻璃合金的玻璃形成能力、过冷液体热稳定性、力学性能及其粉末烧结体的组织和性能等方面的最新研究进展,并对其发展存在的问题进行了探讨。
Al-based metallic glasses（MGs）exhibit high strength,high toughness,and good corrosion resistance.Especially,Al-based MGs possess high special strength which is up to 330kN·m/kg.Therefore,Al-based MGs are promising for applications as a new type of structural materials in aerospace fields.In recent years,Al-based MGs with high glass-forming ability（GFA）and high supercooled liquid stability have been developed,and the MG samples in bulk form have been produced via copper mold casting and consolidation of Al-based MG powders as well,which will promote their practical use.In this paper,the research progress in the development,GFA,stabilization of supercooled liquid,and mechanical properties of Al-based MGs,together with the structure and properties of sintered Al-based MGs powder are reviewed.The problems during the development of the alloys are discussed.
