A fully analytical description of the control of the cross-correlated cross relaxation of multiple-quantum coherences in the presence of local dynamics under heteronuclear double-resonance radio-frequency (RF) irradiation is presented. The contribution of ...
A systematic study was carried out to assess property changes in CaCu3Ti4O12 thin films upon annealing in air in order to evaluate the impact of oxygen vacancies on their colossal dielectric constant behavior. Highly preferentially oriented thin-film sampl ...
The change of length upon heat treatment of steel jacketed, Nb3Sn cable-in-conduit conductors (CICC) is driven by the difference of coefficient of thermal expansion between Nb3Sn and the other components. The cold work of the steel jacket also plays an imp ...
Our work is devoted to the development of YAG:Ce3+ nanoparticle based films for white LEDs. Very stable suspensions of YAG:Ce nanoparticles are synthesized by a glycothermal method at relatively low temperature (300 degrees C). Protected annealing in a sil ...
Face-centered cubic (fcc) to body-centered cubic (bcc) martensitic transformations occur in many materials, such as steels, FeNi meteorites or brass. The phenomenological theory has been the accepted theory for these transformations for more than half a ce ...
The internal friction phenomenon in metallic and polymeric shape memory materials is analyzed. The experimental results permit validation of a theoretical model which describes qualitatively the temperature dependence of the internal friction for the inves ...
Microstructures, and especially grain boundary populations, are characterized in a γ/γ′ nickel-base superalloy submitted to various thermomechanical treatments involving hot deformation and subsequent supersolvus annealing. The resulting microstructures co ...
Recrystallization characteristics of severe cold rolled Cu-0.23 vol%Al2O3 alloy were investigated through the examination of properties and microstructure. A special change of mechanical and physical properties was observed during the annealing process, wh ...
This article describes the microstructure and Charpy impact properties of an Fe-14Cr-2W-0.3-Ti-0.3Y(2)O(3) oxide dispersion strengthened (ODS)-reduced activation ferritic (RAF) steel, manufactured either from elemental powders or from an Fe-14Cr-2W-0.3Ti p ...
This paper presents the results of an experimental study related to the thermal effects on kaolin clay cyclic mobility. The thermal effects were identified by comparing the experimental results of cyclic triaxial tests performed at high temperature (90 C) ...
