چکیده انگلیسی
This paper attempts to highlight emerging issues when joining dissimilar metal pairs by magnetic pulse welding. For this purpose, joint of Al/Cu and Al/Al welded with the same parameters are compared. Al/Cu combination involves a formation of an interfacial intermetallic phase whereas Al/Al joint is bonded by metal continuity at the interface. The intermetallic is found to be amorphous, nanoporous, and damaged by a multi-directional cracks. The formation of such features is respectively explained by a melting confined at the interface followed by high rate cooling, cavitation phenomenon and solidification shrinkage. Mechanical characterizations of the Al/Cu joint show brittle fracture at the interface with fragmentation of the [0] intermetallics (glass type rupture). The intermetallic defects such as pores and cracks strongly reduce the breaking load level when compared to the Al/Al case. On the other hand, the Al/Al joint shows ductile fracture with plastic deformation of the interface.
