## Description
- description: "Bulk titanium diboride – niobium diboride ceramic composites were
consolidated by spark plasma sintering (SPS) at 1950 °C. SPS resulted in dense
specimens with a density exceeding 98% of the theoretical density and a multimodal
grain size ranging from 1 to 10 μm. During the SPS consolidation, the pressure
was applied and released at 1950 °C and 1250 °C, respectively. This allowed obtaining
a two-phase composite consisting of TiB2 and NbB2. For these ceramics composites,
we evaluated the flexural strength and fracture toughness and room and elevated
temperatures. Room temperature strength of thus produced bulks was between 300
and 330 MPa, at 1200 °C or 1600 °C an increase in strength up to 400 MPa was observed.\r\nMicrostructure
after flexure at elevated temperatures revealed the appearance of the needle-shape
subgrains of NbB2, an evidence for ongoing plastic deformation. TiB2–NbB2 composites
had elastic loading – stress curves at 1600 °C, and at 1800 °C fractured in the
plastic manner and strength was ranged from 300 to 450 MPa. These data were compared
with a specimen where a (Ti,Nb)B2 solid solution was formed during SPS to explain
the behavior of TiB2–NbB2 ceramic composites at elevated temperatures.\r\n"
