Abstract

Alumina-tungsten carbide composite was prepared by a hot-pressing process. It is shown that the mechanical properties of alumina matrix materials could be greatly improved after introducing a dispersion of tungsten carbide particles. Flexural strength and fracture toughness of the Al₂O₃-WC composite added with 6 vol.% WC particles and sintered at 1450°C reached 581 MPa and 5.13 MPam^1/2, respectively. The microstructure of Al₂O₃-WC composite was investigated by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis.
