Microstructure and creep properties of Al/Mg/Al composite clad plates
Due to their poor plasticity and corrosion resistance, as well as their flammability in the air, magnesium alloys are limited in large-scale application. To address the above issues, magnesium alloys can be combined with aluminum alloys with superior plasticity and flame retardancy, resulting in high strength and good plasticity of composite laminates at room temperature, and lighter weight. Therefore, this article selects 5052 aluminum alloy as the outer layer of the laminated plate and AZ31 magnesium alloy as the inner layer material to study the effect of the precipitation of intermediate compounds at the interface of this laminated material under high-temperature creep conditions on the creep properties of the material. The results showed that the layer thickness of Al/Mg/Al laminate composite was about 50 mm. The main orientations of 5052Al alloy were (001) and (101) directions, while the main orientations of AZ31Mg alloy were (01
