Room temperature cathodoluminescence quenching of Er3+ in AlNOEr
Valerie Brien, P. R. Edwards, Pascal Boulet +1
This paper reports a cathodoluminescence (CL) spectroscopic study of nanogranular AlNOErx samples with erbiumcontent, x, in the range 0.5--3.6 at%. A wide range of erbium concentra…
Low cycle fatigue of a nickel based superalloy at high temperature: deformation microstructures
Valerie Brien, B. Décamps
The microstructural characteristics of a single crystalline nickel based superalloy (AM1) tested under high temperature fatigue at 950C are reported. For repeated fatigue (…
Preliminary Synthesis of Carbon Nitride Thin Films by N/CH Microwave Plasma Assisted Chemical Vapour Deposition: Characterisation of the Discharge and the Obtained Films
Paul Kouakou, Valerie Brien, Badreddine Assouar +4
The present work deals with the synthesis of crystalline carbon nitride thin films by microwave plasma assisted chemical vapour deposition in N/CH gas mixture. The discharg…
Low-cycle fatigue of a nickel-based superalloy at high temperature: Simplified micromechanical modelling
Valerie Brien, L. Kubin, B. Décamps
This work is focused on the micromechanical modelling of the low cycle fatigue of the nickel based superalloy AM1 at high temperature. The nature of the activated slip syste…
Structural, chemical and optical characterizations of nanocrystallized AlN:Er thin films prepared by r.f. magnetron sputtering
Valerie Brien, P. Miska, H. Rinnert +2
Nanocrystalline n-AlN:Er thin films were deposited on (001) Silicon substrates by r. f. magnetron sputtering at room temperature to study the correlation between 1.54 m IR photo…
Scratch-induced surface microstructures on the deformed surface of Al-Cu-Fe icosahedral quasicrystals
J. S Wu, Valerie Brien, P. Brunet +2
Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations of sintered Al-Cu-Fe icosahedral quasicrystal (IQC) have been carried out to understand…
