摘要：

The effective connection of 1050 Al and AZ31 Mg was realized by magnetic pulse welding. The maximum tensile-shear force of the dissimilar Al/Mg metal lap joint reached 97% of that of the 1050 Al alloy base material by optimizing the process parameters. The microstructure of dissimilar Al/Mg welded joints was analysed by Scanning Electron Microscope (SEM), Energy Dispersive Spectrometer (EDS) and Electron Backscattered Diffraction (EBSD). The results show that the key to obtaining high shear strength of Al/Mg dissimilar metal joints is mainly due to the following two reasons. On the one hand, grain refinement and element interdiffusion occur at the interface. On the other hand, no intermetallic compounds are formed at the interface.& COPY; 2021 Chongqing University.
