Interface design, mechanism analysis, collaborative optimization and microstructure evolution toward advanced applications: a review of high-performance Ti/Al laminated composites
Source abstract
Abstract
Ti/Al laminated composites combine the high specific strength of titanium with the low density of aluminum, making them highly attractive for lightweight structural applications in aerospace, defense, and biomedical fields. However, their engineering applications are limited by the trade-off between strength and ductility, which originates from brittle intermetallic compounds (IMCs) at the interface. IMCs determine the bonding integrity and also act as preferential sites for crack initiation and delamination. This review systematically explores the process–interface–microstructure–performance–application relationship of high-performance Ti/Al laminated composites. It comprehensively summarizes advanced manufacturing techniques, with particular emphasis on the quantitative correlation between process parameters and mechanical properties. The microstructural evolution during deformation is analyzed from the perspectives of inhomogeneous deformation, strain distribution, and heterogeneous deformation-induced (HDI) hardening, which underpin the physical origins of material strengthening and toughening. Damage accumulation and failure mechanisms under quasi-static and dynamic loading are discussed, focusing on the role of the interfacial IMC layer in crack arrest, deflection, and delamination. Four typical toughening strategies are also evaluated, including crystal structure regulation, alloy design, second-phase reinforcement, and biomimetic structural construction. The integration of multiscale computational simulation and machine learning is highlighted as an effective strategy to advance interface engineering from passive characterization toward active intelligent design. Finally, key challenges and future research directions are outlined, providing a theoretical foundation for the development of high-strength and high-toughness Ti/Al laminated composites.
