Atomistic investigation on the effect of temperature on mechanical properties of diffusion-welded Aluminium-Nickel

Abstract

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.

Effect of temperature on the creep properties of polycrystalline Cu-Ni alloy: insight from molecular dynamics simulation

“…Understanding the mechanism in certain materials is an essential task because it helps shed light on the importance of several behaviors that is of great interest but rather difficult in the practical experiment, especially when it comes to the phenomena under the nanoscale regime [1][2][3]. As the investigation scale becomes smaller, the apparatus utilized needs to be more precise, making it costly, thus rushing for the alternative way for that purpose.…”
