High temperature internal friction measurements of 3YTZP zirconia polycrystals. High temperature background and creep
(Elsevier, 2014)
This work focuses on the high-temperature mechanic properties of a 3. mol% yttria zirconia polycrystals (3YTZP), fabricated by hot-pressureless sintering. Systematic measurements of mechanical loss as a function of temperature ...

Effect of high SWNT content on the room temperature mechanical properties of fully dense 3YTZP/SWNT composites
(Elsevier, 2014)
This paper is devoted to correlate the microstructure and room temperature mechanical properties of single-wall carbon nanotube (SWNT) reinforced 3. mol% yttria stabilized tetragonal zirconia with high SWNT content (2.5, ...

Hardness and flexural strength of single-walled carbon nanotube/alumina composites
(Kluwer Academic Publishers, 2014)
This work adds new experimental facts on room temperature hardness and flexural strength of alumina and composites with 1, 2, 5 and 10 vol% single-walled carbon nanotubes (SWNT) with similar grain size. Monolithic Al2O3 ...

Ultra-fast and energy-efficient sintering of ceramics by electric current concentration
(Nature Publishing Group, 2015)
Electric current activated/assisted sintering (ECAS) techniques, such as electrical discharge sintering (EDS) or resistive sintering (RS), have been intensively investigated for longer than 50 years. In this work, a novel ...

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 ...

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 ...
