High-temperature plastic behavior of TZP-Ni cermets
(Wiley-Blackwell, 2008-02)
The creep behavior of tetragonal zirconia TZP-Ni cermets with metal contents below, close to, and above the percolation limit has been studied. Compressive creep tests were performed on as-received materials and samples ...

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 ...

Sintering and Characterization Studies of NiO
(EDP Sciences, 1986)
Des polycristaux de NiO de haute pureté ont été élaborés par frittage avec et sans charge. Ils ont été caractérisés par microscopie optique et électronique. Leur comportement en fluage a été étudié au dessus de 1200°C.

Creep and diffusion in high Tc superconductors
(EDP Sciences, 1994)
Data from steady-state creep and tracer diffusion tests are presented for the high- $T_{\rm c}$, superconductors YBa 2Cu 3O x, and Bi 2Sri 1.7CaCu 2O y Both compounds exhibit oxygen nonstoichiometry and possess orthorhombic, ...

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 ...

La importancia de la segregación de itrio en la deformación plástica de nanocristales de circonia tetragonal dopada con óxido de itrio (YTZP)
(2005)
Muestras de YTZP (policristales de oxido de circonio dopado con itria) con tamaño medio de grano de 50 nm, puras y con un 10% en peso de diferentes fases vítreas han sido deformadas a carga constante en un rango de temperatura ...

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 ...

Creep-resistant composites of alumina and single-wall carbon nanotubes
(2008)
Composites of alumina Al2O3 ceramic and single-wall carbon nanotubes (SWNTs) have been tested in uniaxial compression at 1300 and 1350 °C (Ar atmosphere), and they have been found to be about two orders of magnitude more ...
