Abstract

The effects of rolling temperature and reductions on the bonding strength, interface and distribution of thickness ratio of the steel/aluminum metal-laminate materials, which were prepared by hot-rolling process, were studied by using bending tests and metallographic microscopy and scanning electron microscopy. The results indicate that the number of bending increases with increasing rolling temperatures below 400°C, whereas decreases after that. The maximum bond strength is obtained at 400°C. With increasing the rolling temperature, the rolling reduction of the aluminum layer increases while the steel layer decreases. At a given total rolling reduction, this leads the difference of reduction between aluminum and steel layer increasing. The number of bending and the bond strength increase with increasing the total rolling reduction. The increment of the number of bending is quite small when the total rolling reduction is ranged from 20% to 30%, but extremely large when the total rolling reduction exceeds 30%. The rolling reductions of both layers increase in direct proportion with the total rolling reduction, and the difference between them gradually diminishes and even towards a leveling.
