Progress of heterogeneous structured particulate reinforced titanium matrix composites
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.
