摘要
Al/Mg双金属材料结合了铝合金和镁合金的性能优势,但界面易形成脆性金属间化合物,影响接头性能。中间层作为界面调控手段,能够有效阻隔Al与Mg的直接反应,优化界面组织,提升连接性能。本文综述了不同类型中间层(低熔点金属、高熔点金属、多元素金属及高熵合金)在复合铸造、焊接等工艺中对Al/Mg双金属界面的影响,总结了各类中间层的作用机制及界面性能变化规律,并展望了未来高性能中间层材料的发展方向。
Al/Mg bimetallic materials combine the performance advantages of aluminium and magnesium alloys,but brittle intermetallic compounds are prone to form at the interface,adversely affecting joint performance.As an interface regulation strategy,interlayers can effectively block direct reactions between Al and Mg,optimize interfacial microstructures,and enhance bonding properties.This paper reviews the effects of different types of interlayers,including low-melting-point metals,high-melting-point metals,multielement alloys,and high-entropy alloys,on the Al/Mg bimetallic interface during processes such as compound casting and welding.The mechanisms of various interlayers and their influence on the interface performance are summarized,and the future development directions of high-performance interlayer materials are also discussed.
