Abstract
The densification behavior of nanocrystalline zirconium diboride (ZrB2) powders with nickel (5â¯vol%) is reported by spark plasma sintering (SPS) technique. SPS experiments were performed at 1600 and 1900â¯Â°C with 65â¯MPa pressure and 1â¯min holding time. A maximum relative density around 95% was obtained after SPS processing of ZrB2 at 1900â¯Â°C while the density of ZrB2 sample sintered at 1600â¯Â°C reached 88% of the theoretical density. Hardness and fracture toughness values are 11â¯GPa and 4.11â¯MPaâ¯m1/2 for the sample sintered at 1600â¯Â°C and 13.7â¯GPa and 2.65â¯MPaâ¯m1/2 for the sample sintered at 1900â¯Â°C, respectively.
