AbstractTo clarify the work hardening discrepancy effect on the strengthening of laminated metals, we designed two laminated Cu/Cu4Zn and Cu/Cu32Zn samples with different layer thicknesses. Cu/Cu4Zn has larger work hardening discrepancy between two constituent layers relative to Cu/Cu32Zn, but the yield strengths of two CuZn constituents are comparable. Uniaxial tensile results suggest Cu/Cu4Zn with larger work hardening discrepancy exhibits a significant strengthening at early deformation stage while Cu/Cu32Zn possesses a better ductility. The underlying mechanisms for the strengthening effect are attributed to more geometrically necessary dislocations accumulated at interfaces and severer strain localization due to the larger work hardening discrepancy. ?? 2022 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology.
