Abstract

A seven layers steel based laminated composite (four ultra-high carbon steel, UHCS, layers and three mild steel, MS, layers) has been processed by rolling bonding and its microstructure and impact properties have been studied. Suitable parameters of temperature and thickness reduction were selected to obtain a finer microstructure relative to the original material components. This finer microstructure induces improved mechanical properties. Charpy impact tests values in both "crack arrester" and "crack divider" orientations improve the values of the UHCS constituent material. Furthermore, the crack arrester orientation value exceed that of the MS material. The delamination, which is controlled by interface bonding, plays a key role deflecting the crack, absorbing energy and imposing the nucleation of new cracks in the next material layer.
