Cette étude concerne l’analyse de la fissuration dans les superalliages base Nickel employés dans les zones chaudes des turbines aéronautiques. Dans ce but, un modèle de propagation de fissure en fatigue incrémental en temps, via des endommagements couplés au comportement élasto-viscoplastique du matériau, est développé à l’aide d’une approche loca...

Epidemiological studies suggest that the main part of chronic effects from air pollution is likely to be linked with particulate matter (PM). Oxidative potential (OP) of PM is gaining strong interest as a promising health exposure metric. This study combined atmospheric detailed composition results obtained for seven different urban background envi...

Many studies have demonstrated associations between exposure to ambient particulate matter (PM) and adverse health outcomes in humans that can be explained by PM capacity to induce oxidative stress in vivo. Thus, assays have been developed to quantify the oxidative potential (OP) of PM as a more refined exposure metric than PM mass alone. Only a sm...

In this paper, we present SuHeXiang Wan, a medicine used in traditional Chinese medicine for the treatment of epilepsy and convulsions. We investigated the antioxidant, anti-inflammatory and neuroprotective activities of the same treatment designated as AT000. The synergy of the two plants, Dryobalanops aromatica and Saussurea lappa, of which the u...

This study aims at observing and understanding the oxidation mechanisms of ZrB2-20 vol%SiC (ZS), HfB2-20 vol%SiC (HS) and HfB2-20 vol%SiC- 3 vol%Y2O3 (HSY) materials up to 2400 °C under water vapour conditions. After SPS sintering, fully densified samples were oxidized at several temperatures with 30 vol% H2O/70 vol% Ar during 20 s. Weight variatio...

Mortars based on different compositions (cast with calcium aluminate cement (CAC), ordinary Portland cement (CEM I), blended Portland cement (CEM III, CEM IV, CEM V) and super sulphated cement (SSC)) were exposed to gaseous H2S. The most soluble phases from cement lead to the presence of ions in a water layer formed on the mortar surface and these ...

Environmental/thermal barrier coatings (E/TBCs) of yttria partially stabilised zirconia (YSZ), gadolinium zirconate (GZO) and a combination of Y2SiO5 and GZO were applied on a Nb/Nb5Si3-based alloy with the nominal composition of Nb-25Ti-8Hf-2Cr-2Al-16Si (at%). A B-containing M7Si6-based (M=Ti, Nb, Fe, Cr) layer produced by pack cementation was use...
