“…This research also shows a new opportunity to design nanoscale reactive films with different multilayer arrangements to control reaction propagation beyond existing technology . A comparative study of the reaction multilayer foils Ni/Ti, produced by two different methods, magnetron sputtering and accumulative roll bonding, were carried out . Reliable joints of TiNi to Ti6Al4V were obtained, with shear strength of 35 MPa in case of accumulatively rolled foils, and 88 MPa when magnetron sputtered foils were used.…”

“…At high reaction temperatures, very low activation energy equal to 26 kJ mol −1 was obtained, which suggests diffusion of Ni in molten Al is the rate controlling mixing mechanism in agreement with the conclusions of other studies focused on un‐mediated Al/Ni reactive multilayers. However, as the reaction temperature decreases the activation energy appears to shift to much larger values implying a change in the reaction mechanism, which indicates that solid products are able to form earlier in the reaction at these temperatures, impeding atomic diffusion and intermixing . One more novel method designed for investigation mechanisms of N2M reactions, that should be mentioned here, is a unique non‐adiabatic bomb calorimeter to measure heat generated by nanocomposite metallic foils .…”

Non-isothermal processes in nanometric metallic multilayers are reviewed, both experimentally and theoretically. The Ni/Al nanofoil is considered as a model system. On the one hand, the experimental methods of elaboration and analysis are presented and, on the other hand, the modeling approach at the macroscopic and atomic scale. The basic experimental features are reported together with recent achievements. Molecular dynamics investigation of the reactivity of Ni/Al systems is reported for bulk systems and nanosystems including nanoparticles, nanowires, nanofilms, and multilayers. The focus is on atomic-scale modeling versus experiments. Molecular dynamics approaches allow us to elucidate the mechanisms of nonisothermal processes occurring in nanoscale systems, such as phase transformations and self-propagation reactions.

This research studies the structure and mechanical properties of Ni/Ti multilayered composites produced from commercial pure Ni and Ti foils by accumulative roll-bonding technique. To investigate these properties, scanning electron microscopy, Vickers microhardness, and uniaxial tensile tests were conducted at different processing cycles. Studies showed that in terms of structure, Ni and Ti layers maintain their continuity even up to 10 cycles of accumulative roll-bonding. Moreover, the energy-dispersive spectroscopy in scanning electron microscopy detected no deformation induced diffusion or reactive interfacial zones. It was found that by increasing the accumulative roll-bonding cycles, tensile and yield strengths as well as the hardness of the composite enhance and the total elongation reduces continuously.

“…Usually, metals or alloys possess distinct properties. One approach to adding new properties to already existing material is utilization of bi-metal or bi-alloy composites, which combine several prominent properties together, such as high mechanical properties, high wear resistance, high corrosion resistance, high thermal expansion coefficient and light weight (Della Volpe and Siboni, 2022;Awad and Nasser, 2020;Saneei Mousavi et al, 2020;Emadinia et al, 2016;Apalak et al, 2022).…”

Materials and alloys usually possess distinct properties. In contrast to conventional materials, employment of bi-metal laminates allows achievement of better performance in various properties, such as light density, high strength, high corrosion and wear resistances. Moreover, considering the agriculture machinery and equipment, there is a growing demand for utilization of advanced materials with improved mechanical properties and durability. Bonding (RB) process is one of the new novel methods for production of bi-metal laminates. The study presented explores the asymmetric roll bonding for the purposes of fabrication of bi-metal Al/Br laminates with thickness reduction ratios 10–30% with mismatch speed ratios of 1 : 1.05, 1 : 1.1 and 1 : 1.15. Furthermore, finite element simulation of roll bonding process was investigated using ABAQUS software. Additionally, to improve the bonding strength, the effect of mismatch speed ratios was investigated. Finally, utilizing the scanning electron microscopy (SEM), the bonding surface morphology of samples was studied.
