High-Temperature Mechanical Spectroscopy of Nitrogen-Rich Ca-alpha-SiAlON Ceramics
Daniele Mari, Robert Schaller, Mehdi Mazaheri
Nitrogen-rich Ca-alpha-SiAlON ceramics made with different starting powder compositions have been studied by high-temperature mechanical spectroscopy in parallel with compressive deformation in a spark plasma sintering equipment. The mechanical loss spectr ...
2011Reverse precipitation synthesis and characterization of CeO2 nanopowder
In the present work, CeO2 nanopowder was synthesized via a reverse precipitation method using CeCl3 center dot 7H(2)O, NH4OH and sodium dodecyl sulfate as raw materials. The effect of thermal treatment on the crystal growth, surface area and chemical bonds ...
2010Sintering behavior of an ultrafine alumina powder shaped by pressure filtration and dry pressing
Master sintering curve (MSC) was used as a practical approach to analyse the sintering behavior of an ultrafine alumina powder. Non-isothermal sintering was carried out at three heating rates. The concept of the MSC has been used to investigate the effect ...
2010Enhanced electrical conductivity of ultrafine-grained 8Y(2)O(3) stabilized ZrO2 produced by two-step sintering technique
Two-step sintering of nanocrystalline zirconia powder stabilized with 8 mol% yttria resulted in remarkable enhancement of the electrical conductivity and significant suppression of the accelerated grain growth. The electrical conductivity of the nearly ful ...
2010High temperature mechanical spectroscopy of yttria stabilized zirconia reinforced with carbon nanotubes
Daniele Mari, Robert Schaller, Mehdi Mazaheri
High temperature mechanical properties of zirconia reinforced with carbon-nanotubes (CNTs) are studied by mechanical spectroscopy. CNTs limit zirconia grain-boundary sliding (GBS) and consequently deformation. Concurrent grain-growth and plastic deformatio ...
