| Abstract(in English) | Recently, carmakers have adopted the use of aluminum for is used as a weight reduction material. And, technology that welds aluminum to copper is therefore necessary for producing W/H (Wire Harnesses). When the dissimilar metals such as aluminum and copper are welded by ultrasonic welding, a solid-state welding, it was found that metal crystals at the interface are joined and microscopic crystals are formed by the strong processing. In addition, weak intermetallic compounds are not found on the weld interface. Intermetallic compounds on the welding interface are generated and enlarged by thermal load. Welding interfaces that contained intermetallic compounds with a layer sickness of 10μm had a 30% reduction in tensile strength. |
