摘　　要：层状复合钛合金是由不同种钛合金制成的、成分和组织性能逐层变化的先进材料,能够发挥多种钛合金的性能。层状复合金属的结构设计是保证成形性能和满足服役需求的前提。增材制造相比传统制造技术,具有设计灵活便捷、试制周期短、可成形复杂结构等优势,在层状复合钛合金研制领域应用广泛。本文介绍了层状金属直接过渡、成分过渡和阻挡层过渡结构设计方法,综述了几种增材技术研制层状复合钛合金,包括激光定向能量沉积、电弧熔丝增材制造和电子束熔丝增材制造的研究进展。围绕过渡区组织性能优化、热处理制度建立、残余应力控制和失效机制判据等方面,展望增材制造层状复合钛合金未来的发展方向。Layered composite titanium alloy(LCTA)is a type of advanced material composed of various titanium alloys.The composition and property of LCTA change gradually along specific directions,which realizes the combination of various performances.The structural design of layered composite alloys is crucial to ensure formability and meet service requirements.Compared with traditional manufacturing technology,additive manufacturing has the advantages of flexible design,short trial production cycle,and easily forming complicated structure,which have been widely used to manufacture LCTA.In this paper,the direct bonding,composition transition and inter-layer transition structural design strategies of layered composite alloys were introduced,and the research progress of additive manufacturing LCTA,including laser-directed energy deposition,wire and arc additive manufacturing,and electron beam directed energy deposition were reviewed.In the final section,the future development of LCTA was also discussed based on transition layer structural optimization,heat treatment strategy exploration,residual stress control,and failure criteria establishment.
