説明:

Reactive consolidation of tantalum monoboride (TaB) was performed by spark plasma sintering at 2150 °C. The TaB ceramic had elongated grains with a length/width ratio between 2.4 and 4.8 and a length between 30 and 100 μm. Up to 3 vol.% of residual non-reacted boron was also present. The hardness, indentation fracture toughness and room-temperature strength of the TaB were 18.5 ± 0.2 GPa, 9.8 ± 0.4 MPa m1/2, and 320 MPa, respectively. The TaB showed resistance to high-temperature deformation as its flexural strength gradually increased from 370 MPa at 1000 °C to 425±7 MPa at 1800 °C.
