The exothermic reactions in the nanostructured aluminum (Al)/nickle (Ni) multilayer foils were analyzed. The room-temperature soldering of stainless steel specimens using Al/Ni foils was also studied. X-ray diffraction, differential scanning calorimetry and optical measurements were used to characterize the products, heats and the velocities of the reactions. The results show a tensile shear strength of 48 MPa for the reactive foil joints as compared to 38 MPa for conventional joints.
