Due to the size effect, nano-multilayer films have a melting point depression effect, which has obvious advantages for the joining of temperature-sensitive materials. At the same time, the violent and rapid exothermal reaction between the nano-multilayer films provides a huge heat for the materials joining process. Therefore, when the nanomultilayer film is applied for joining, it can serve in brazing or diffusion bonding as an auxiliary interlayer layer, and on the other hand, it can serve as an independent heat source to provide heat for the SHS joining. The real-time observation of the reaction process of nano-multilayer films is limited by the conditions of single lens shooting speed and measurement accuracy. In addition, the application of molecular dynamics simulation has opened up new ideas for the research of nanomultilayer film reaction mechanism.
