“…This is principally because the ductile layer can serve as the compliant layer to suppress the initiation and propagation of residual stress placed on cracks near the interface [ 14 ]. Lin et al [ 16 ] prepared an SiC f -Ti/Al 3 Ti laminated composite by using the vacuum hot-pressing sintering method and found that SiC fibers can provide strengthening and toughening effects for the brittle intermetallic and the laminated composites. The strengthening mechanism of the SiC f -reinforced intermetallic layer still needs to be clarified.…”

Ti/Ti–Al and SiCf-reinforced Ti/Ti–Al laminated composites were fabricated through vacuum hot-pressure using pure Ti foils, pure Al foils and SiC fibers as raw materials. The effects of SiC fiber and a laminated structure on the properties of Ti–Al laminated composites were studied. A novel method of fiber weaving was implemented to arrange the SiC fibers, which can guarantee the equal spacing of the fibers without introducing other elements. Results showed that with a higher exerted pressure, a more compact structure with fewer Kirkendall holes can be obtained in SiCf-reinforced Ti/Ti–Al laminated composites. The tensile strength along the longitudinal direction of fibers was about 400 ± 10 MPa, which was 60% higher compared with the fabricated Ti/Ti–Al laminated composites with the same volume fraction (60%) of the Ti layer. An in situ tensile test was adopted to observe the deformation behavior and fracture mechanisms of the SiCf-reinforced Ti/Ti–Al laminated composites. Results showed that microcracks first occurred in the Ti–Al intermetallic layer.

“…This increase is due to the formation of new interfaces between the matrix and fibers, which enables processes such as crack deflection, load transfer, [21] and the release of residual thermal stresses. Additionally, both the fibers themselves and processes such as fiber debonding, fiber bridging, [27] and fiber deformation fracture [8] absorb energy during deformation, contributing to the increase in toughness. [24] Compared with the introduction of other fibers, NiTi fibers can undergo reversible transformation between austenite and martensite, induced by stress or temperature.…”

A novel method of preparing continuous NiTif reinforced Ti/Al laminated composites were proposed via ultrasonic consolidation (UC) and vacuum hot pressing (VHP). The microstructure of the composites was characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), and electron back scattering diffraction (EBSD). The tensile properties of the composites were measured by universal testing machine. Results indicated that the composite exhibits multi‐layer structure consisting of residual NiTi fiber, intermetallic compounds (IMCs) layer, reaction layer, Ti layer and Al layer. The intermetallic layer is composed of Al3Ti and Al3Ni, and some Ni‐rich precipitates dispersed in the matrix. And with the introduction of UC assisted, grain refinement occurred at the IMC/Al interface, texture variation emerged at the NiTi fiber/IMCs interface, a weakening of texture strength is observed at both interfaces. Compared to NiTif reinforced Ti/Al laminated composites without UC assisted, both the tensile strength (from 872.4 MPa to 826.5 MPa) and failure strain (from 17.5% to 20.4%) of NiTif reinforced Ti/Al laminated composites with UC assisted increased due to the contribution of UC assisted. The reinforcing and fracture mechanisms of the UC assisted are also discussed.This article is protected by copyright. All rights reserved.
