摘　　要：近年来以空天飞行器为代表的国家重大战略装备蓬勃发展,对轻质、高强钛基复合材料(TMCs)的需求呈高速增长趋势,并促使其向高性能化方向发展。在复合化的基础上“师法自然”,对组织进行构型化设计是提高钛基复合材料综合性能的有效途径。构型化组织中软硬相间的变形协调作用与异质变形诱导的强化和应变硬化效应能够显著提升材料的加工硬化能力,并获得理想的强塑性协同效果。本文围绕材料研制的各个环节,从基元复合技术、构型化复合工艺途径、组织特征与力学性能等方面综述了钛基复合材料构型化复合的研究现状,深入讨论了构型化组织的共性特征与强韧化机理,总结了目前研究存在的问题与技术难点,并指出钛基复合材料构型化复合的未来发展方向。In recent years,the development of the high-speed aircraft and other major strategic equipment has growing demand for lightweight,high-performance titanium matrix composites(TMCs).Imitating the nature to design the heterogeneous microstructure is an effective way to improve the comprehensive performance of TMCs.The heterogeneous deformation-induced strengthening and strain-hardening effects between the soft and hard phases can significantly enhance the work-hardening ability of the TMCs and obtain the desirable strength-ductility synergy effect.This paper overviewed the current research on hetero-structured TMCs,containing the design techniques,fabrication process,microstructure characteristics and mechanical properties,discussed in depth the common features and strength-ductility synergy mechanism of hetero-structured TMCs,summarized the problems and technical difficulties of the current research,and pointed out the future directions.
