“…Beside the in-situ method to investigate the properties of the nanomaterial that can be performed experimentally [6], MD simulation has shown its ability in the investigation of these properties. Some researchers have indicates that the data obtained by the MD simulation also have shown good agreement with the experimental works [82,83,94,95,[86][87][88][89][90][91][92][93]. Therefore, using MD simulation to investigate those properties is reasonable, either in its good agreement or to reduce the cost of research, and also there are broad ranges of techniques to make sure that the MD simulation performed is could be validated [96] to maintain its correctness.…”

Carbon-nanotubes (CNTs) and Nanowires (NWs), the two nanomaterials with outstanding properties, are the materials with which their behaviour and properties have long been drawing attention to researchers. However, the tiny nature of these two materials causes difficulties in describing and estimating their behaviour and properties, thus a numerical technique that considers the tiny nature of the materials like Molecular Dynamics (MD) simulation is a promising solution to this problem. Since the early utilization of MD simulation in the investigation of the behaviour of carbon-nanotubes and nanowires, it provides the researcher with an excellent description of how the two materials behave at atomic-scale and then estimate their properties. Recently, MD simulation of CNTs and NWs exhibit growth in the simulation size as with the growth of the computing capabilities. The size of the materials being simulated by MD simulation increased significantly in the recent year, thus giving possibility to achieve a better description of the behaviour and a more precise estimation of the properties. In this review, we provide an overview of the recent advances in the investigation of the joining processes and properties of carbon-nanotubes and nanowires at atomic-scale utilizing molecular dynamics simulation.

“…This process is demonstrated in Figure 8(a). Meanwhile, specific nano-welding from CNT onto Ni substrate has been demonstrated by Liu et al [82]. They have shown that the nanowelding of CNT and the Ni substrate could be accomplished at a temperature of 1500 K which is below the melting point of Ni (1726 K).…”

“…The method of MD simulation is mainly built by the solution of the Newtonian equation of motion numerically which runs under a particular ensemble of atoms where can be used to investigate the material behaviors [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. In the application of diffusion welding, there are several investigations using MD simulation like, Chen et al when perform an investigation of diffusion bonding between Cu-Ag [5] and Cu-Al [6] which revealing the mechanism of diffusion bonding and shed light on the importance of pressure, temperature, and surface roughness on the process.…”

Joining two or more parts one of the industrial manufacturing processes required to satisfy the shape that either for functionality and appearance [1]. Several joining techniques have been proposed to satisfy these needs, and have shown very good performance for several applications, such as joining both similar and dissimilar metals [2]. By tracing the history of joining processes, at the first place, joining processes requires sort of fusion between the two, which in some cases will either reduce the performance of the material and sometimes also introducing several crack growth and embrittlement because it involves rapid solidification processes, thus heat treatment is necessary [3]. Furthermore, these techniques require other complex techniques to achieve an optimum parameter makes it economically not applicable [4]. Nowadays, solid-state welding in which the fusion of the materials during joining processes could be avoided is introduced. One of the methods of solid-state welding that is now widely used is diffusion-welding. Instead of only could be used for joining pure materials that are less complex, these techniques could also deal with the more complex materials ranging from alloys, compounds, several polymers, and so forth.

“…The capability of handling various broad applications of materials investigations and the advantages offered by MD simulation has led many studies to adopt this method, including those that were conducted to figure out the influence of several parameters in various welding techniques that are critical during the process of welding and their impact on the mechanical properties. Specifically for the diffusion welding process, MD simulation has shown great results, which not only revealed atomistic behavior, as it can be visualized by several software tools [4,5], but some mechanical properties can also be estimated and validated by this method [6][7][8][9][10][11][12][13][14][15][16][17].…”

This paper presents an investigation of diffusion welding of aluminum and nickel at the atomic scale by utilizing molecular dynamics simulation. By employing several temperature and pressure values, the significant influence of the two could be obtained and thus the optimum parameter values could be obtained. The results showed that the bonding mechanism is mostly promoted by Al, in which the deformation and defects are involved. The results on both the mechanical properties and the evolution of the diffusion configuration showed that temperature has more impact compared to pressure. It was indicated that by raising the temperature to 700 K with the lowest pressure (50 MPa), both the mechanical properties and the evolution of the diffusion configuration showed a relatively significant difference. On the one hand, the deformation that occurs during welding, which is mostly caused by raising the temperature, obviously promotes joining and therefore more joining depth can be achieved, although it results in a curved diffusion zone at the interface. On the other hand, it also leads to a lower ultimate tensile strength. During the tensile test, raising the temperature also led to focusing the deformation in the diffusion zone, while a lower temperature resulted in a wider area of deformation.
