A novel approach for preparing Cu/Al laminated composite based on corrugated roll

In this paper, Cu/Al laminated composite was prepared by a novel approach, corrugated + flat rolling (CFR) method, with low reduction ratio of 20% per pass, and the microstructure and mechanical properties were investigated. The results indicate that the preliminary combination of the composite can be realized by the first CFR pass and the composite with complete combination was obtained after the flattening rolling process. The corrugated bonding interface was formed without intermetallic phase, and the grain refinement (especially at the interface) occurred after the CFR process. Furthermore, the Cu/Al laminated composite with corrugated bonding interface exhibits outstanding tension-shear and tensile properties.
