    Abstract: A method of joining a first component and a second component that are made of dissimilar metals. In some embodiments, the method comprises applying friction between the first component and the second component sufficient to generate a layer of quasi-liquid metal and produce shear localization within the quasi-liquid metal at a dissimilar metal interface between the first component and the second component and terminating the application of friction at a predetermined time after generation of the quasi-liquid metal. In some embodiments, the method comprises applying amorphous metal between at least a portion of the first component and the second component at a dissimilar metal interface, heating the amorphous metal to a temperature between its glass transition temperature (Tg) and the lowest melting temperature of the components involved, and applying compression pressure to generate thermoplastic deformation of the amorphous metal.
