Abstract
A conventional process chain for the manufacturing of steel-clad aluminum strips using roll bonding comprises many auxiliary operations. These steps include the surface preparation of steel and aluminum strips as well as heat treatment for an interfacial diffusion control. Twin-roll casting provides an efficient alternative way to join these metals. In this process a thin solid steel strip is fed between two revolving rolls together with an aluminum melt. The melt solidifies rapidly to a thin layer which is subsequently deformed in the roll gap. For a comparison of the mechanisms and conditions of joining using these two methods, a series of experiments of roll bonding at a temperature near the melting point of aluminum were carried out. The minimal hot deformation strain necessary for a satisfying bonding quality was identified. The results of roll bonding experiments and twin-roll cast trials related to clads’ microstructure and mechanical properties were compared.
