Abstract：

The Mg alloy plate AZ31 and Al alloy plate 6061 were successfully fabricated by the extrusion compound process, and the influences of different blank layers on the microstructure and mechanical properties of AZ31/6061 composite plate were investigated by SEM, EDS, optical microscope, EBSD and tensile testing machine. The results show that the Mg alloy layer in the extruded composite plate contains much fine recrystallized grains as well as a small amount of deformed grains, and the Al alloy layer has elongated fiber structure with a large amount of fine recrystallized grains. Besides, the excellent metallurgical bonding of Mg/Al interface is produced, and the interfacial reaction layer with various thicknesses exists Mg2Al3 in P1 composite plate, Mg2Al3 (Al side) in P2 composite plate and Mg17Al12(Mg side) in P2 composite plate.
