This talk addresses current developments and applications of reactive and non-reactive nanomultilayers for joining dissimilar materials and miniaturized components at ever-lower temperatures. First, the application of reactive nanomultilayered foils for reactive joining of a wide variety of dissimilar materials at room temperature in air is presented, emphasizing the dominant role of the thermal properties of the base components on the reactive joining characteristics. General guidelines for tailoring the exothermal reaction, solders and metallizations are given in order to achieve optimum reactive joining processes for different material combinations. Next, the development of novel low-temperature nanojoining technologies on the basis of nanomultilayered filler coatings will be presented. Here, the melting-point depression of nanoconfined metals in combination with short-circuit diffusion in nanostructured materials is exploited to achieve fast, directional mass outflow, which can be utilized for localized bonding.
