“…Moreover, we made a breakthrough that the failure strain of Ti-Al 3 Ti-Al laminated composites is almost 15 times that of Ti-Al 3 Ti laminated composites reported in the literature. 15,16 According to reports, 7,15,16 the highest compressive strength and failure strain of Ti-Al 3 Ti laminated composite are 1328 MPa and 2.3%, respectively. The failure strain of Ti-Al 3 Ti-Al laminated composites (35%) is significantly enhanced due to the addition of the 1060 Al foil, and the fraction of low-angle grain boundary (represented by green line) is high (46%) (Figure 1(b)).…”

In order to further improve the mechanical properties of Ti-Al3Ti laminated composites, the endothermic semisolid reaction was used to fabricate Ti-Al3Ti-Al laminated composites, and the quasi-static compressive test, dynamic compressive test, and the ballistic penetration test were conducted on these composites. The results showed that the compressive strength and failure strain of Ti-Al3Ti-Al laminated composites prepared at 660°C are 1432 MPa and 35%, respectively. The dynamic response of these composites has obvious strain rate effect, and the crack grows in the shape of “Z.” The V50 of Ti-Al3Ti-Al targets is 509 m s−1. To sum up, Ti-Al3Ti-Al laminated composites have better mechanical properties and anti-penetration properties compared to Ti-Al3Ti laminated composites.

“…Nevertheless, under the loading parallel to the layers, the compression strength of Ti-(SiC f /Al 3 Ti) composite was decreased significantly in comparison with that of Ti/Al 3 Ti MIL composite. Jiao et al 19 prepared a continuous carbon fiber-reinforced Ti/Al 3 Ti MIL composite via the combination of ultrasonic consolidation and HP sintering techniques. It suggested that the compressive strength and fracture strain of C f -Ti/Al 3 Ti MIL composite were slightly lower than that of Ti/Al 3 Ti MIL composite when the load is parallel to the layers.…”

Shape-memory alloy titanium nickel (NiTi) fiber was introduced into continuous ceramic aluminum oxide (Al2O3) fiber-reinforced titanium–titanium trialuminide metal–intermetallic laminated (CSMAFR-MIL) composite using vacuum hot pressing (HP) sintering method to improve the microstructure and mechanical properties of the composite. Scanning electron microscopy, energy-dispersive spectroscopy, and X-ray diffraction techniques were employed to characterize the microstructure of the novel CSMAFR-MIL composite. Besides, the tensile tests were carried out on continuous Al2O3 fiber-reinforced Ti-Al metal–intermetallic laminated (CFR-MIL) composite and the CSMAFR-MIL composite to explore the influence of NiTi fiber additive on mechanical behavior of the CFR-MIL composite. The experimental results showed that the intermetallic layer including Al3Ti, Al3Ti0.8V0.2, Al3Ni intermetallics but without residual NiTi fiber was generated via the reactions of liquid Al with NiTi fiber and Ti foil during preparation. Moreover, owing to the addition of NiTi fiber, intermetallic centerline was prevented effectively to form in the CSMAFR-MIL composite. Moreover, the elemental diffusion occurred between the Al2O3 fiber and the intermetallic, revealing that the metallurgical bonding was formed during the fabrication process. Furthermore, the CSMAFR-MIL composite possessed higher strength and superior ductility than those of CFR-MIL composite attributed to the microstructure optimization.

“…Therefore, CF is a promising reinforcement to prepare high-performance TMCs, which can be expected to make up the aforementioned shortcomings of Ti alloys.Currently, continuous long CFs are often applied to fabricate high-strength TMCs. [19][20][21][22][23] Even et al [24] adhered long CFs on the surface of titanium alloy powder by viscous organic polymers and then used hot isostatic pressing (HIP) to produce continuous CFs-reinforced TMCs under the conditions of 600À700 C, 200 MPa, and 1 h. The composites were all above 98% in density and the ultimate tensile strength (UTS) reached 600 MPa at room temperature.

Titanium (Ti) and its alloys possessing high specific strength, specific stiffness, good heat and corrosion resistance, and a relatively low density are widely used as structural materials in aviation, aerospace, automotive, biomedical, and many other industry fields. [1][2][3] TiÀ6AlÀ4V (TC4) is the most representative Ti alloy because of its overall excellent room-temperature properties. [4,5] However, the high-temperature mechanical properties of the TC4 alloy are relatively poor. The current working temperature of TC4 is lower than 500 C, which is much lower than some other alloys such as steel and nickel-based superalloys. [6,7] In addition, Ti alloys usually have poor electrical and thermal conductivity (around 10 W/ (m K)), [8] which greatly limits their applications. [9][10][11] Introducing reinforcements with high strength and high thermal conductivity in Ti alloys to make a Ti matrix composite (TMC) is an effective method to improve its overall properties. [12][13][14] Carbon fiber (CFs) is a fiber material with excellent physical, mechanical, and thermal properties. Its diameter is on the level of several micrometers, while the length can reach up to centimeters. This characteristic makes them not only possess high aspect ratios but also be easier to disperse homogeneously in metal matrices compared with nanocarbon reinforcements. [15][16][17] The density of CFs is only %1.80 g cm À3 (40% of Ti) but the axial tensile strength of CFs is above 3.5 GPa (>300% of Ti). CFs' high-temperature resistance ranks among the top in all chemical fibers, [18] which are shown to be ultrahigh temperature (over 2000 C) resistant in the nonoxidizing environment. Last but not least, the thermal conductivity of CFs is around 5000 W/(m K) (%500 times of Ti). Therefore, CF is a promising reinforcement to prepare high-performance TMCs, which can be expected to make up the aforementioned shortcomings of Ti alloys.Currently, continuous long CFs are often applied to fabricate high-strength TMCs. [19][20][21][22][23] Even et al. [24] adhered long CFs on the surface of titanium alloy powder by viscous organic polymers and then used hot isostatic pressing (HIP) to produce continuous CFs-reinforced TMCs under the conditions of 600À700 C, 200 MPa, and 1 h. The composites were all above 98% in density and the ultimate tensile strength (UTS) reached 600 MPa at room temperature. Yang et al. [25] used copper-coated continuous CF cloth as reinforcement and TC4 as matrix. After they were compressed and stacked on top of each other, CF cloth/TC4 composites were manufactured by spark plasma sintering (SPS). The compressive yield strength (YS) increased by 370 MPa compared with TC4 matrix at a strain rate of 4200 s À1 because of the tight interface bonding. Overall, the fabrication process of the aforementioned continuous CFs-reinforced TMCs is complicate. In addition, they can only achieve good performance in certain specific directions, showing anisotropic characteristics.
