摘要

In this study, a Mg/Al composite plate with superior ductility was successfully prepared by introducing ultrathin Zn foil interlayer. The influences of Zn interlayer on the microstructure and mechanical performance of Mg/Al composite plate were comprehensively investigated. Our results demonstrate that the Mg/Al-Zn plate shows good interfacial bonding, and Mg-Zn intermetallic compounds with a thickness of about 1 μm are formed at the interface. The Zn interlayer is conducive to refining the grain size of Mg layer and also weakening the texture intensity of both Al and Mg layers. The Mg/Al-Zn plate has a slightly higher tensile strength than Mg/Al plate, but with a significantly higher elongation of about 16.8%.
