摘　　要：铝基非晶合金具有优异的力学性能与良好的耐蚀性,但是其较差的非晶形成能力使得大尺寸样品不易获得,工程应用也由此受到很大限制。鉴于合金的非晶形成能力与其结构密切相关,本文简要回顾铝基非晶合金发展历程,在全面了解其组元构成的基础上,重点阐述了铝基非晶合金的微观结构,以及由此衍生出的合金成分设计理论、非晶形成能力与成分的关系、晶化过程中初生相的选择等问题。最后对铝基非晶合金未来的研究方向进行了展望。Although Al-based amorphous alloys have excellent mechanical properties and good corrosion resistance,their poor glass-forming ability makes large-scale samples difficult to obtain,limiting their engineering applications.Owing to the close relationship between the glass-forming ability of alloys and their structure,the development of Al-based amorphous alloys is first briefly reviewed to gain a thorough understanding of their component composition.On this basis,the microstructure,composition design theory,relationship between glass-forming ability and composition,and selection of primary phase during crystallization in Al-based amorphous alloys are discussed.Finally,the future study directions for Al-based amorphous alloys are prospected.
