“…The transgranular mode indicates that the sintering process is going to be completed; hence, the temperature of 1850 ºC is enough for the densification of these composites. The same mode of fractures for ZrB 2 -SiC composites at 1700 and 1850 ºC have been reported in other research works [27,[29][30].…”

“…Hot pressing of a ZrB 2 sample with a particle size of 2.1 µm at 2000°C for 1 hour under a pressure of 30 MPa resulted in a relative density of 91% [9]. With the addition of SiC, a relative density of 99.8% was achieved for a ZrB 2 (~2 µm) composite containing 30 [17]. By hot pressing ZrB 2 composites containing SiC and ZrO 2 at 1850 ºC for 1 h under 30 MPa in vacuum the relative densities more than 98% were achieved.…”

ZrB 2 -SiC-C f composites containing 20-50 vol% short carbon fibers were hot pressed at low sintering temperature (1450 ℃) using nanosized ZrB 2 powders, in which the fiber degradation was effectively inhibited. The strain-to-failure values of such composites increased with increasing fiber content, and the value for the composite with 50 vol% C f was even more than 3 times higher than that of the composite with 20 vol% C f . Furthermore, the composite exhibited non-brittle fracture mode when the fiber content was above 30 vol%, and the thermal shock critical temperature difference of the composite with 30 vol% C f was up to 727 ℃, revealing excellent thermal shock resistance of this composite. Additionally, ZrB 2 -SiC-C f composites displayed good oxidation resistance when the fiber content was below 40 vol%, suggesting that this method provides a promising way for preparation of high-performance ZrB 2 -SiC-C f composites at low temperature.
