Abstract:A new method was proposed for preparing AZ31/1060 composite plates with a corrugated interface, which involved cold-pressing a corrugated surface on the Al plate and then hot-pressing the assembled Mg/Al plate. The results show that cold-pressing produces intense plastic deformation near the corrugated surface of the Al plate, which promotes dynamic recrystallization of the Al substrate near the interface during the subsequent hot-pressing. In addition, the initial corrugation on the surface of the Al plate also changes the local stress state near the interface during hot pressing, which has a large effect on the texture components of the substrates near the corrugated interface. The construction of the corrugated interface can greatly enhance the shear strength by 2-4 times due to the increased contact area and the strong “mechanical gearing” effect. Moreover, the mechanical properties are largely depended on the orientation relationship between corrugated direction and loading direction.
