Abstract

Low carbon steel plate and pure aluminum plate were used as raw materials, the self-developed cold-hot roll bonding technology was used to prepare aluminum/steel laminated composite plate, the flexural properties, interface diffusion layer thickness and intermetallic compounds of aluminum/steel laminated composite plates were characterized by 90° repeated bending test, OM (optical microscope), SEM (scanning electron microscope) and EDS (energy spectrum analysis), the effects of cold rolling reduction, hot rolling reduction and hot rolling temperature on the interfacial bonding properties of aluminum/steel laminated composite plates were analyzed, the influence mechanism of cold-hot roll bonding process on the interfacial bonding properties of aluminum/steel laminated composite plates was discussed. The results show that the bending resistance of aluminum/steel laminated composite plates increased with increasing the cold rolling reduction or the hot rolling reduction, and increased first and then decreased with increasing the hot rolling temperature. The effect of cold rolling reduction, hot rolling reduction and hot rolling temperature on the bending resistance increased in turn. Under the condition of cold rolling reduction of 45% and hot rolling reduction of 35–50%, when the hot rolling temperature was 400 °C, the interface diffusion layer thickness of aluminum/steel laminated composite plates was 1.5–2.5 μm, no intermetallic compounds within the interface, and the interfacial bonding properties increased with increasing the interfacial diffusion layer thickness; when the hot rolling temperature was 500 °C, the interface diffusion layer thickness was 3–5 μm, and the spherulite FeAl3 phase intermetallic compound with diameter less than 5 μm distributed in the interface, the interfacial bonding properties increased with increasing the interface diffusion layer thickness; when the hot rolling temperature was 600 °C, the interface diffusion layer thickness was 8–14 μm, the intermetallic compound was Fe2Al5 phase with 6–12 μm thickness, and the interfacial bonding properties decreased sharply.
