N2 - In this study, we report a novel approach to enhance strength and stiffness in titanium alloys while maintaining ductility. We prepared a two-scale laminated structured titanium matrix composite (TMC) using graphene nanoplatelets (GNPs) introduced into a Ti6Al4V matrix. The intrinsic structure of the GNPs was preserved, and an appropriate interface reaction facilitated strong bonding. Strengthening and toughening effects were achieved through uniform distribution, diverse interface designs, firm interface bonding, and laminated architecture. Our results demonstrate that the laminated GNPs/Ti6Al4V composite exhibits excellent strength-ductility synergy, with an enhanced yield strength (+163.35 MPa compared to pure Ti6Al4V) while maintaining a good ductility of 17.39%. This study presents a practical approach to achieving a balance between strength and ductility in titanium matrix composites.
