| Popis: | The use of Al/Ni multilayer powders as a new heat source has been expected for metal joining technique owing to their instantaneous reaction and enormous amount of exothermic heat. In this study, the effects of the amount of Al/Ni multilayer powders on the electrical and mechanical properties of the joining part of Al strip specimens were examined. These electrical and mechanical properties were estimated by electric resistivity measurement using the four-terminal method and shear test, respectively. Experimental results show that Al specimens are successful joined under a limited condition and exhibit low electrical resistance and sufficiently high strength to maintain the joined state. However, overheating increases the amount of Al/Ni multilayer powder in the joined part, which causes considerable damage such as voids and dissolved loss. It is found that optimization of the amount of Al/Ni multilayer powder enables us to realize reliable joining of Al foils in electronics fields in the future. |
