N2 - MnO2/Pb nanocomposite was produced by solid-state accumulative roll-bonding (ARB) technique. Composites with different amounts of MnO2 were synthesized with the highest probable ARB cycles. The mechanical properties of composites were studied by tensile, microhardness and shear punch tests. It was observed that yield stress, tensile stress and elongation were improved by increasing the ARB cycles. On the other hand, increasing the amount of MnO2 up to 0.5 wt.% improved the mechanical properties of the composites. Tensile tests results revealed that the maximum tensile strength could be achieved in the composite containing 0.5 wt.% MnO2 after 10 passes (up to 4.35 times higher than control sample, Pb-10 pass). In comparison with Pb-10 pass, the hardness of 0.5 wt.% MnO2/Pb nanocomposite was enhanced up to 7.5 times after 10 ARB passes. ARB process led to a proper distribution of MnO2 particles in Pb matrix with the mean size of less than 30 nm.
