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 layer in the rolling process of a steel/aluminum/aluminum alloy laminated composite plate with a thickness more than 4 mm, and the problem of uncoordinated deformation is solved due to the large difference in the properties of steel, aluminum and aluminum alloy.

Abstract: The invention belongs to the technical field of metal micro-forming, and in particular relates to a method for inflating micro-channels. The present invention is aimed at the problems of low process flexibility, single product type, and non-closed structure of the micro-channel when preparing metal micro-channels by micro-plastic forming of ultra-thin metal strips. The present invention uses a method combining numerical simulation and bond rolling experiment to analyze the effect of the hydrogen pressure and bond strength of the metal composite ultra-thin strip after bond rolling on the pore diameter of the micro-channel, and the corresponding relationship between the micro-channel pore diameter and the titanium hydride content, heating temperature, and bond strength of the metal composite ultra-thin strip is obtained. The present invention has no special requirements on molds, wide selection of metal materials, low requirements for equipment capabilities; closed tubular micro-channel products with different pore diameters and different distributions can be prepared according to requirements, with rich product categories and high process flexibility.
