The microstructural evolution of deformed 304L stainless steel during static recrystallization and grain growth was characterized by EBSD within an SEM chamber, which enabled microstructural and crystallographic information to be determined. The experiment ...
Solid oxide fuel cell cathodes have been examined using non-destructive x-ray nanotomography. The cathodes examined were a composite of strontium-doped lanthanum manganite (LSM) and yttria-stabilized zirconia (YSZ), with three different starting powder siz ...
The main aim of this work was to study and understand the influence of SiC particles on the corrosion and tribocorrosion of Al-matrix composite materials. For that, Al-SiCp functionally graded composites were produced by centrifugal casting and different S ...
A model based on the Euler-Bernoulli theory is used to assess the sensitivity of residual stresses in solid oxide fuel cells to the mechanical properties and geometry of the constituents. It considers different cell configurations, characterised by the pre ...
Coupled grain boundary motion was simulated in a three-dimensional nanocrystalline Al grain boundary network using molecular dynamics. It is shown that, in spite of the triple junction constraints, a symmetrical Sigma 75 tilt boundary can migrate during th ...
Titanium oxide due to its optical properties, such as high refractive index, transparency to visible light and photocatalytic properties is being used in a large number of devices such as micro-optical elements and solar cells. The fabrication of TiO2 micr ...
Oxygen permeability measurements of Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) disk shaped membranes fabricated by thermoplastic processing and sintered at different temperatures (1000–1100 °C), showed no influence of the grain size on the oxygen permeation fluxes. T ...
(La0.6Sr0.4)0.95FeO3-δ/ Sm0.2Ce0.8O2 (70:30 w/w) and (La0.6Sr0.4)0.995Co0.2Fe 0.8O3-δ/Gd0.1Ce0.9O 2 (50:50 w/w) cathodes screen printed on anode-supported cells were tested for 500 h under different conditions by using a Taguchi matrix that combined cathod ...
The Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steel was fabricated by mechanical alloying of a pre-alloyed, gas atomised powder with yttria nano-particles, followed by hot isostatic pressing and ther ...
High zirconia refractories are composed of a zirconia skeleton surrounded by an intergranular glassy phase. In these materials, zirconia undergoes up to two successive phase transitions during the manufacturing process, c → t then t → m. This leads, after ...
