## Title

- title: Reactive consolidation and high-temperature strength of HfB2–SiB6
  title_type: original
  lang: en

## Description

- description: During the spark plasma sintering at 1900 °C, SiB6 decomposes into
    cubic silicon carbide and boron carbide, owing to the reducing environment of
    the furnace. For the HfB2-SiB6 ceramic improvement in hardness (24.5 ± 0.7 GPa)
    was attributed to the formation of the B12(C,Si,B)3. Fracture toughness by indentation
    (6.8 ± 2.4 MPa·m1/2), single-edge notched bend specimens (4.6 ± 0.4 MPa·m1/2)
    and room-temperature strength (513 ± 21 MPa) of the HfB2–SiB6 composite produced
    by spark plasma sintering was higher or on the same level as the HfB2–SiC ceramics.
    The high-temperature flexural strength tests suggested that the strength would
    decrease monotonically with an increase in temperature. At or below 1600 °C, only
    a linear stress-strain response was observed, and resulted into a mean strength
    of ~320 MPa. During the tests at 1800 °C, we observed a nonlinear deformation
    indicating ongoing plastic deformation which led to a strength decrease down to
    230 ± 30 MPa.
