摘要：

The Al/Mg alloy were successfully prepared by the combined method of powder metallurgy and rolling. The microstructure and interface bonding strength of the Al/Mg interface under rolling and annealing temperatures were investigated. The results indicates that, the Al/Mg interface is only physically bonded after rolling, but metallurgical bonding can be achieved after annealing. When the annealing temperature is 200 degrees C, the shear strength of Al/Mg interface is the maximum, which is 37.06 MPa. With the increase of annealing temperature, the thickness of interfacial layer increases gradually. When the annealing temperature was 400 degrees C, a typical three-layer structure was formed in the Al/Mg interface. Micro-area XRD analysis showed that Mg32Al47Cu7, Al3Mg2 and Al12Mg17 phases were generated at the interface.
