Abstract

Fully dense ZrCW matrix composite was fabricated by reactive infiltration technique, where molten Zr₂Cu alloy infiltrated into a porous WC preform at 1300 °C in vacuum. The ZrCW composite exhibits a core-shell structure feature: gray WC cores were enveloped by bright tungsten shells, which are homogeneously distributed in the ZrC matrix. X-ray diffraction and transmission electron microscopy investigation show that nano-sized Zr _xCu_yC_z particles were formed in the ZrC matrix. The Vicker's hardness, flexural strength and fracture toughness of the ZrCW composite are measured as 14.5 GPa, 615 MPa and 11.7 MPa m^1/2, respectively. Crown
