Abstract
Disclosed is a corrugated-flat rolling composite method for a steel/aluminum/aluminum alloy laminated composite plate. According to the method, a steel/aluminum laminated composite plate with a good plate shape and a firmly bonded interface is prepared, the corrugated cold rolling with a large thickness ratio is utilized to enhance the deformation of the interface to be bonded, and the deformation of constituent metals is coordinated to solve the problem that the steel-aluminum interface is not deformed. Then the deformation of constituents is coordinated by the interfacial corrugated-flat hot rolling to achieve the bonding of aluminum and aluminum alloy surfaces and prepare a high-performance steel/aluminum/aluminum alloy laminated composite plate. Taking the advantage that the interface oxidation has little effect on the bonding of aluminum and aluminum alloy, the problem of anti-oxidation in the composite process is eliminated, thereby the problem of low interfacial bonding strength is solved due to a fact that the interfacial shear becomes weak and the interfacial bonding mainly depends on the hot-press action when the steel and aluminum bonding surface approaches the neutral l…
