AI Technical Summary
Existing rolling composite processes for preparing aluminum/magnesium/aluminum layered metal composite plates suffer from problems such as deformation incoordination due to the difference in properties between magnesium and aluminum, small interfacial deformation, interfacial oxidation, and low bonding strength. In particular, it is difficult to prepare three-layer or higher layered metal composite plates.
A method combining low-temperature hot pressing and high-temperature rolling is adopted. The aluminum/magnesium/aluminum layered composite slab is preheated and hot rolled using a hot pressing die with a three-dimensional array of protrusions on its surface. The three-dimensional protrusion array structure increases the interface contact area, coordinates metal deformation, avoids interface oxidation, and improves the bonding strength.
It effectively solved the problem of interface oxidation during high-temperature rolling, improved the interfacial bonding strength and overall performance of aluminum/magnesium/aluminum layered composite plates, and achieved stable preparation of three-layer and above metal layered composite plates.
