“…22–25 These intermetallic compounds and their structures determine the performance of the joint. 26 In this area, Yazdani et al 27 studied the fabrication of Al-matrix nanocomposites reinforced by mono-dispersed TiAl3 intermetallic three-step process of cold-roll bonding, heat-treatment, and accumulative roll bonding. According to their research, the initial Ti particles have been totally converted into TiAl3 intermetallic and achieved a heat treatment process at 590°C for 2 h, which caused coarse formation TiAl3 particles on the interface of the original Al plates.…”

In this paper, for the first time, dual-phase Mg-Li alloy is used to produce a three-layered Al/Mg/Al composite with the use of the cold roll bonding process. The low density and high ductility are known as the essential advantages of the Mg-Li alloys, while a couple of important problems should be taken into account, namely low corrosion resistance and low strength. It has been tried to deal with the mentioned problems by performing cold work and cover the Mg sheet with the Al similar plates. To investigate the Mg-Al layers bonding quality, mechanical properties and microstructure were examined for different thicknesses reduction ratio. The peeling test results showed that with increasing rolling pressure, the size and number of cracks on the brittle surfaces due to brushing, surface expansion, and metal extrusion between the cracks were improved by rising the reduction thickness ratio, bond strength enhanced, sharply. The UTS of 33.33% thickness reduction three-layered Al/Mg sample was obtained 186.5 MPa, which was more than 2.1 and 1.3 times higher than the initial Al1050 and MgLZ91 samples, respectively. However, because of increasing the amount of thickness reduction, roll-bonded layers’ quality, the tensile strength of the composite, and the microhardness of both layers increased. Furthermore, the elongation has reduced, and the maximum ultimate tensile strength and microhardness were achieved at 66.67% thickness reduction.

“…2 In recent times, intermetallic compounds formed in situ, such as TiAl 3 and NiAl 3 , have gained popularity in AMCs because of their low density, high melting points, and high strength. [12][13][14][15] Recently, many researchers have studied the effect of reinforcement size and volume fraction on AMC performance.

Recently, Ti–Al intermetallic compound-reinforced Al matrix composites have attracted increasing attention because of their high specific modulus, strength, and thermal stability. In this study, blended powders of Ti and Al were ball milled and fabricated to in situ Ti–Al intermetallic compound-reinforced Al matrix composites by cold-pressing and hot-pressing sintering. The microstructures and component of core–shell-like structure in reinforcement were observed and analyzed. Material properties including hardness, density, and compression performance were tested and analyzed according to experimental processes. The results indicate that the time point of compression in hot-pressing sintering is crucial to obtain the closed core–shell-like structures. Based on the orthogonal experimental data, entropy methods and technique for order preference by similarity to ideal solution were combined to select the process parameters (ratio of Ti and Al, milling time, sintering temperature, holding time, and compaction pressure) for the best comprehensive performance of Vickers hardness and compressive yield strength.

“…Finally, the bonding time is very short, and thus the volume fraction of IMCs formed at the bonding interface is greatly reduced. Many studies have shown that the inclusion of an aluminum (Al) [24][25][26], copper (Cu) [28,29], nickel (Ni) [22], or silver (Ag) [23] interlayer increases the strength of hot-roll diffusion-bonded Fe-Ti joints [17][18][19]30] and suppresses the formation of IMCs [29][30][31][32][33][34]. However, even though a small improvement in the bonding strength is achieved, the bonding strength at the joints is still limited by the formation of brittle IMCs at either the Ti/interlayer or the interlayer/SS interface.…”

This study performed experiments and thermodynamic calculations to elucidate the effects of diffusion temperature on interfacial evolution and mechanical properties of pure titanium and carbon steel (i.e., steel) sheets bonded via a new type of multi-pass continuous hot-roll diffusion with nickel interlayer. The interfacial evolution results revealed that this new type of multi-pass continuous hot-roll diffusion treatment showed a very good adherence due to its metallurgy bonding, because it made a remarked improve to between compound and intermetallic compounds relationship. Secondly, in mechanical properties results revealed that the highest shear strength (∼470 MPa) was obtained at a processing temperature of 850°C. The highest peel strength (∼21 N/mm) was obtained in the sample processed at 900°C. Bonding temperatures above and below these levels reduced the bond strength respectively due to poor atom diffusion and excessive compound formation, resulting in joint failure at the Ti-Ni interface. Extensive cleavage planes with various alignments were observed on the fracture surfaces in these cases. Overall, a hot-rolling temperature of 850°C was found to provide the optimal tradeoff between interfacial bonding strength and ductility. This work provided an economical and convenient solution for broadening the engineering application of interface between sheets of pure titanium and steel.
