摘　　要：非晶合金具有良好的物理和化学性能,但尺寸问题限制了其实际应用,而焊接技术可以突破其应用瓶颈。非晶合金焊接方法可分为液相焊接和固相焊接,两类方法焊接过程中非晶接头形成方式不同,有效避免晶化是获得高质量接头的关键,本文就非晶合金焊接领域的研究进行了系统全面的梳理与归纳,综述了非晶合金/非晶合金焊接、非晶合金/晶态金属焊接的研究现状,重点阐述了不同焊接方法获得完全非晶态焊件的特点与局限,同时本文还综述了非晶合金作为钎料的研究现状,分析了非晶钎料的应用前景,并总结了提高非晶钎料钎焊接头力学性能的方法,继而对非晶合金焊接研究及发展提出了展望。Metallic glasses with excellent physical and chemical properties are hindered by their size constraints,limiting their practical applications.However,welding technique holds the potential to overcome these limitations.Welding methods of metallic glasses can be classified into liquid phase welding and solid phase welding,each involving distinct mechanisms to form amorphous joints.Effective preventing crystallization is crucial for obtaining high quality joints.This paper provides a systematic and comprehensive review of the research in the field of metallic glass welding,and summarizes the research status of metallic glass and metallic glass welding as well as metallic glass and crystalline metal welding.It focuses on the characteristics and limitations of different welding techniques to achieve fully amorphous welded parts.Additionally,it reviews the research status of metallic glasses as solder materials in brazing process and analyzes the potential applications of metallic glass-based brazing materials,and summarizes approaches for enhancing the mechanical properties of brazed joints.Finally,this paper outlines prospects for the future research and development of metallic glass welding.
