Room-temperature soldering of gold-coated stainless-steel specimens was investigated using freestanding Al/Ni nanostructured multilayer foils and freestanding AuSn solder layers. Thicknesses of the reactive foils were varied in order to optimize the joining of the stainless-steel specimens and to minimize the heating to the specimens. The reaction products of the Al/Ni foils, and the heats and the velocities of the reactions were characterized using x-ray diffraction (XRD), differential scanning calorimetry (DSC), and optical measurements.
