Outline
Discontinuously reinforced titanium matrix composites （DRTMCs） exhibit outstanding properties including light weight， heat resistance， high strength， corrosion resistance， and deformability， holding immense promise for applications in aerospace， marine engineering， and biomedical fields，etc. This work systematically reviews the fabrication，processing，and typical properties and applications of DRTMCs. In terms of fabrication， the advantages and limitations of melting casting， powder metallurgy， and additive manufacturing in densification， reinforcement management， and forming scale are analyzed， and reinforcement architecture design with its strength-ductility synergy mechanisms is elaborated. In terms of processing， the influence of reinforcement alignment and matrix recrystallization during hot working on mechanical properties is discussed， along with constraints in cold deformation such as reinforcement fracture and shear band formation. Challenges in welding and machining arising from reinforcement introduction are identified， and advances in joint strengthening strategies and energy-field-assisted machining are reviewed. Regarding applications， typical properties of DRTMCs are summarized， and industrial cases， including hot-formed large-scale components， cold-formed precision sheets and wires， and near-net-shape powder metallurgy parts， are presented. Finally， key future research directions are proposed， encompassing multi-scale biomimetic architecture design， iterative upgrading of in-situ synthesis processes， deep development of additive manufacturing， synergistic control of cold/hot deformation and heat treatment， innovation in joining and machining technologies， and advancement toward industrial-scale application.
