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. ER -
