How to improve the bonding ability and quality perform between heterogeneous plates has always been one of the difficult issues that have long been concerned in the field of high-performance heterogeneous composite plate forming and manufacturing. This paper proposes a new method for manufacturing heterogeneous composite panels—composite panels by hard-plate rolling (HPR). In addition to adding hard plates above and below the aluminum/magnesium/aluminum (Al/Mg/Al) composite slab, the research results of the hot rolling process of the composite plate with or without the hard plates at 40%, 60%, and 80% reduction show that the hard plates can be rolled During the manufacturing process, the shear stress in the rolling direction (RD) is partially converted into the compressive stress in the normal direction (ND), which then increases the welding pressure between the heterogeneous composite laminates, which can inhibit the occurrence of bending and edge cracks, and significantly improve the quality and shape of the board ability. At the same time, through the study of the interface structure of the composite plate, it can be known that metallurgical bonding can be achieved with a small reduction after the addition of the hard-plate, and two clear layers of Al3Mg2 and Al17Mg12 intermetallic compounds appear at the Al/Mg interface, and the thickness of the diffusion layer is uniform. Significantly larger than the traditional hot-rolled composite board, the thickness of the diffusion layer can reach 38µm under the condition of 60% reduction under the action of the hard-plate, the yield strength is 172.3MPa, and the elongation reaches 21.5%. In summary, the hot-rolled by hard-plate is high forming and manufacturing of performance heterogeneous composite panels provides a method.
