摘要：
Based on fusion bonding and atomic interdiffusion between the liquid ceramic and molten Ti-based alloy, the laminated composites of TiB2-based ceramic and Ti-6Al-4V alloy were achieved by centrifugal reactive casting, and within the interlaminar region the composite microstructures of nano-structured gradient developed with the continuously-graded evolution of TiB2 and TiB in spatial size. Interlaminar shear strength, flexural strength and fracture toughness reach to 335±35 MPa, 862 ±45 MPa and 45±15 MPa·m0.5, respectively. © 2018, Science Press. All right reserved.
