Improvement of Vickers hardness measurement on SWNT/Al2O3 composites consolidated by spark plasma sintering
(Elsevier, 2014)
Dense alumina composites with different carbon nanotube content were prepared by colloidal processing and consolidated by Spark Plasma Sintering (SPS). Single-wall carbon nanotubes (SWNTs) were distributed at grain boundaries ...

Spark Plasma Sintered Zirconia Ceramic Composites with Graphene-Based Nanostructures
(MDPI, 2018)
The addition of graphene-based nanostructures (GBNs) can improve the inherent fragility of ceramics and provide them with improved electrical and thermal conductivities. However, both the starting material (ceramic matrix ...

Creep behavior of TiCxN1-x-CoTi cermets synthesized by mechanically induced self-sustaining reaction
(Elsevier, 2011-03)
The plastic flow of TiCxN1−x–CoTi cermets has been investigated by uniaxial compression tests carried out in argon atmosphere at temperatures between 1100 and 1200 ◦C. Two different cermets, with 5 wt.% W or WC content ...
