Popis: A three-layer material based on B4C/Al, B4C/TiB2 and B4C composites had been successfully prepared. The microstructures and properties of B4C/Al-B4C/TiB2-B4C composite were investigated in detail. The three-layer porous preform was first prepared by hot pressing. Then the three-layer composite was fabricated by infiltrating aluminum into the porous preform in vacuum. The three-layer B4C/Al-B4C/TiB2-B4C composite showed good interfacial bonding. When using the B4C ceramics layer as the load-bearing surface, the flexural strength, fracture toughness and Vickers hardness of the composite were 230 MPa, 3.4 MPa·m1/2 and 38 GPa, respectively.
