摘要：

The densification behavior of nanocrystalline zirconium diboride (ZrB2) powders with nickel (5 vol%) is reported by spark plasma sintering (SPS) technique. SPS experiments were performed at 1600 and 1900 degrees C with 65 MPa pressure and 1 min holding time. A maximum relative density around 95% was obtained after SPS processing of ZrB2 at 1900 degrees C while the density of ZrB2 sample sintered at 1600 degrees C reached 88% of the theoretical density. Hardness and fracture toughness values are 11 GPa and 4.11 MPa m(1/2) for the sample sintered at 1600 degrees C and 13.7 GPa and 2.65 MPa m(1/2) for the sample sintered at 1900 degrees C, respectively.
