| Abstract Scope |
Lap joining of dissimilar steel and aluminum alloys are successfully conducted in solid state by electrically assisted pressure joining. During joining, electric current is directly applied to the specimen assembly under compressive plastic deformation. In the meantime, different holding time of the pulsed current also induced to enhance the joint strength. Microstructural analysis confirms that the joint is successfully fabricated in solid-state for the selected material combination. The result of mechanical tests shows that the strength and fracture mode of the joints are strongly affected by the amount of the plastic deformation and the electric current intensity. The result of mechanical tests also shows that an optimal thickness reduction corresponding to the maximum fracture load can be found for a given current intensity. The present study confirms that the concept of electrically assisted pressure joining is applicable to joining of dissimilar materials. |
