Deformation mechanisms in yttria-stabilized cubic zirconia single crystals
(Walter de Gruyter, 2010)
This work attempts to give a unified picture of the microscopic mechanisms which control the plastic deformation in yttria-stabilized cubic zirconia single crystals, particularly for the soft orientation (uniaxial compression ...

Evidence of nanograin cluster coalescence in spark plasma sintered α-Al2O3
(Elsevier, 2013)
The aim of this study is to elucidate the coarsening kinetics involved during densification of fine-grained pure α-alumina by spark plasma sintering. Low temperature and short dwell time sintering conditions were used to ...

Mechanical and electrical properties of low SWNT content 3YTZP composites
(Elsevier, 2015)
Fully dense 3mol% Y2O3-ZrO2 (3YTZP) composites with low single wall carbon nanotube content (0.5, 1 and 1.5vol% SWNT) were prepared by colloidal processing and spark plasma sintering (SPS). SWNT were distributed at ceramic ...

Creep study on alumina and alumina/SWCNT nanocomposites
(Elsevier, 2018)
Alumina and alumina/SWCNT nanocomposites have been sintered by spark plasma sintering, obtaining relative densities higher than 99%. Microstuctural characterization revealed a grain microstructure in the submicron range, ...

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 ...

Influence of the processing route on the carbon nanotubes dispersion and creep resistance of 3YTZP/SWCNTs nanocomposites
(Wiley-Blackwell, 2015-02-01)
3YTZP matrix composites containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250C, following different processing routines with the aim of optimizing the SWCNTs ...

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 ...

Exotic grain growth law in twinned boron carbide under electric fields
(Elsevier, 2018)
Grain growth is a ubiquitous phenomenon in all materials, and it affects both structural and functional prop- erties. Despite its intrinsic importance, a full comprehension of grain growth from a fundamental point ...
