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, ...

High temperature creep of 20 vol%. SiC-HfB2 UHTCs up to 2000 °C and the effect of La2O3 addition
(Elsevier, 2018)
High temperature compressive creep of SiC-HfB2 UHTCs up to 2000 °C has been studied. Microstructural analysis after deformation reveals formation of new phases in the Hf-B-Si and Hf-B-Si-C systems, which are responsible ...

Intragranular carbon nanotubes in alumina-based composites for reinforced ceramics
(Springer Nature, 2019)
The traditional methods for the synthesis of reinforced alumina-based matrix composites with carbon nanotubes (CNTs) have presented serious difficulties for obtaining well-dispersed and homogeneously distributed CNTs within ...

Enhanced carbon nanotube dispersion in 3YTZP/SWNTs composites and its effect on room temperature mechanical and electrical properties
(Elsevier, 2016-10)
In this work, several modifications of the colloidal processing technique and spark plasma sintering (SPS) to prepare yttria tetragonal zirconia composites (YTZP) with single walled carbon nanotubes (SWNT) have been ...

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 ...
