“…Figure 12a shows that the texture of the Al 3 Ti phase is oriented along the <001> direction, aligning with previous studies. [52,55] Upon closer examination in Figure 12a,c, it is evident that after UC assisted, there is a shift in texture within area 1 from the <001> direction to the <110> direction. Similarly, from the comparison in Figure 12b,d, it is observed that after UC assisted, there is no significant texture transformation occurred in area 2.…”

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.

“…Additionally, NiAl can be used as the reinforcing element in MLCs [24,25]. MLCs that have an intermetallic reinforcing element (including NiAl) are known as metal-intermetallic laminate (MIL) [26] composites. MIL composites are typically synthesized through hot pressing of alternating stacked metal foils so that intermetallic layers form in an interdiffusion and chemical reaction while sufficient pressure ensures the contact between the metal foils [27,28].…”

In this study, SHS was used to produce metal-intermetallic-ceramic laminate AlMg6-NiAl-TiC composite. The experiment conducted without a cylindrical powder pellet holder produced no joint between the NiAl and AlMg6 sheet. On the other hand, the experiment conducted inside a cylindrical powder pellet holder (CPPH) with a blind hole produced a joint. It was found that the AlMg6 sheet had a temperature of 400–550 °C across its entire thickness during SHS. The study of the microstructure and energy-dispersive analysis (EDS) of AlMg6-NiAl-TiC composite showed that it had five layers: (1) ceramic layer of 7-mm-thick TiC; (2) the upper diffusion layer that formed at the interface between NiAl and TiC consisted of TiC + NiAl; (3) an intermetallic layer, which consisted of 13-mm-thick NiAl; (4) the lower diffusion layer, which formed at the interface between NiAl and AlMg6; and (5) a layer of 4-mm-thick aluminum alloy AlMg6. The EDS showed that during the synthesis of NiAl and its interaction with the surface of the AlMg6 sheet, mixing of the components of the initial materials (NiAl, AlMg6) in the joint interface occurs. At the interface of NiAl and AlMg6, the microhardness was 790–870 HV, which indicates the presence of quenching structures in the melted zones.
