摘要：

Dissimilar material welding between 1 mm-thick magnesium and aluminum alloy plates in lap form was performed using the MIG process with zinc foil as the interlayer material. The zinc foil acted as a barrier layer that restrained reactions between the aluminum and magnesium atoms, and a crack-free lap joint of dissimilar materials was obtained. The interfacial layer between the fusion zone and the unmelted magnesium substrate was mainly composed of Mg-Zn binary intermetallic compounds. The tensile strength of the lap joint was 64 MPa, and a fracture occurred at the interface between the fusion zone and the unmelted magnesium alloy. (C) 2011 Elsevier B.V. All rights reserved.
