Spark plasma sintered tantalum carbide–carbon nanotube composite: Effect of pressure, carbon nanotube length and dispersion technique on microstructure and mechanical properties

TaC–NbC formed by spark plasma sintering with the addition of sintering additives

“…Initial parameters were chosen to match that of TaC in a previous study from our research group and then refined after performing a controlled study investigating densification as a function of changes in temperature and pressure. 21) The sintered samples were cylindrical in shape with a thickness of approximately 5 mm and a diameter of 20 mm for the samples prepared with a pressure of 60 MPa and diameter of 15 mm for the sample prepared at 100 MPa.…”

Investigation of the microstructure, mechanical properties and cell viability of zirconia-toughened alumina composites reinforced with carbon nanotubes

“…In addition, An et al 28) reported that CNTs in alumina matrix decrease mass transportation during sintering and inhibit the densification process. Bakhsh et al 10) demonstrated that…”

Microstructure and Mechanical Properties of Nanofiller Reinforced Tantalum-Niobium Carbide Formed by Spark Plasma Sintering

“…The addition of CNTs to ceramic matrices also enhance sintering and densification due to the increased interparticle diffusion as a result of the high thermal and electrical conductivity of the CNTs between the ceramic grains [49,50].…”

“…Longer CNTs have a greater surface area that allows a greater load to be transferred between the matrix and CNTs. Bakshi et al [49] prepared…”

“…The resulting properties are shown in Table 4. Table 4: Properties of TaC and TaC-4 wt.% CNT compacts prepared by SPS [49].…”
