Abstract:

Three-phase porous composites containing electrolyte (ionic conductor), electronic conductor, and porosity phases are frequently used for solid oxide fuel cell (SOFC) electrodes. Performance of such electrodes is microstructure sensitive. Topological connectivity of the microstructural phases and total length of triple phase boundaries are the key microstructural parameters that affect the electrode performance. These microstructural attributes in turn depend on numerous process parameters including relative proportion, mean sizes, size distributions, and morphologies of the electrolyte and el

Abstract:

Li-O2 batteries have been attracting increasing attention and R&D efforts as promising power sources for electric vehicles (EVs) due to their significantly higher theoretical energy densities compared to conventional Li-ion batteries.

Abstract:

There are many potential advantages to welding structural ferritic steels with a power-beam process such as electron beam welding. These include low distortion, high welding speed, and computer control. The microstructure developed by a typical EB weld is poor from a mechanical properties perspective, however, and this limits the applications in which it is used. This work investigates the microstructures developed in an EB welded structural steel with the aim of further understanding and promoting a sound microstructure. A single steel composition was welded using a wide range of conditions.

Abstract:

Nanocrystalline Fe10 %Zn and Fe30 %Zn alloys have been prepared from pure elemental powders by mechanical alloying processing in a high energy planetary ball-mill. Microstructural, structural, and magnetic characterizations of the powders were investigated by X-ray diffraction, and vibrating sample magnometer. The crystallite size reduction to the nanometer scale is accompanied by an increase in the atomic level strain. The reaction between Fe and Zn leads to the formation of a bcc Fe(Zn) solid solution with a lattice parameter close to (0.2912 nm for Fe30 %Zn and 0,2885 nm for Fe10 %Zn)

Abstract:

On etudie par microscopie (meb, met, eels, edx) et par analyse par sonde ionique (sims) les composites prepares par impregnation de fibres de sic par depot chimique en phase vapeur de si::(3)n::(4) ou sic. On etudie l'influence du substrat sur la microstructure des depots, puis on caracterise la microstructure et la composition chimique de fibres elementaires de sic revetues par cvd de c et de sic. L'analyse des fibres revetues et tout particulierement de l'interface fibre/matrice montre la complementarite des methodes eels et sims pour caracteriser les composites a fibres longues
