2D versus 3D-like electrical behavior of MXene thin films: insights from weak localization in the role of thickness, interflake coupling and defects
Sophia Tangui, Simon Hurand, Rashed Aljasmi +6
MXenes stand out from other 2D materials because they combine very good electrical conductivity with hydrophilicity, allowing cost-effective processing as thin films. Therefore, th…
Effect of severe thermo-oxidative aging on the mechanical behavior and fatigue durability of short glass fiber reinforced PA6/6.6
Florent Alexis, Sylvie Castagnet, Carole Nadot-Martin +2
The work deals with the fatigue lifetime estimation of Short Fiber Reinforced Thermoplastics (SFRP), with a focus on conjugated effects of thermal aging. Two materials containing 3…
Influence of generated defects by Ar-implantation on the thermoelectric properties of ScN
R. Burcea, J. -F. Barbot, P. -O. Renault +9
Nowadays, making thermoelectric materials more efficient in energy conversion is still a challenge. In this work, to reduce the thermal conductivity and thus improve the overall th…
Nanoindentation-induced deformation twinning in MAX phase TiAlN
Christophe Tromas, Salomé Parent, Wilgens Sylvain +6
Plastic deformation mechanisms have been investigated in the MAX phase Ti2AlN. Nanoindentation has been used to induce plastic deformation in a single grain, and a Transmission Ele…
Observation of Bulk Plasticity in a Polycrystalline Titanium Alloy by Diffraction Contrast Tomography and Topotomography
J. C. Stinville, W. Ludwig, P. G. Callahan +4
The mechanical properties of polycrystalline metals are governed by the interaction of defects that are generated by deformation within the 3D microstructure. In materials that def…
P-type behavior of CrN thin films by control of point defects
Arnaud le Febvrier, Davide Gambino, Fabien Giovannelli +5
We report the results of a combined experimental and theoretical study on nonstoichiometric CrN1+d thin films grown by reactive magnetron sputtering on c-plane sapphire, MgO (100)…
Time resolved evolution of the 3D nanoporous structure of sintered Ag by X-Ray nanotomography: role of the interface with a copper substrate
Kokouvi Happy N'Tsouaglo, Xavier Milhet, Jérôme Colin +6
The evolution of the nanoporous structure of cylindrical sintered silver samples during high temperature aging, ranging from 200 {\textdegree}C to 350 {\textdegree}C for 350 min, i…
X-ray ptychographic topography, a new tool for strain imaging
Mariana Verezhak, Steven Van Petegem, Angel Rodriguez-Fernandez +7
Strain and defects in crystalline materials are responsible for the distinct mechanical, electric and magnetic properties of a desired material, making their study an essential tas…
One MAX phase, different MXenes: a guideline to understand the crucial role of etching conditions on TiCT surface chemistry
Mohamed Benchakar, Lola Loupias, Cyril Garnero +13
MXenes are a new, and growing, family of 2D materials with very promising properties for a wide variety of applications. Obtained from the etching of MAX phases, numerous propertie…
Room temperature deformation in the FeMo -Phase
Sebastian Schröders, Stefanie Sandlöbes, Carola Birke +4
The role of TCP phases in deformation of superalloys and steels is still not fully resolved. In particular, the intrinsic deformation mechanisms of these phases are largely unknown…
Multiscale modeling of the elastic behavior of architectured and nanostructured Cu-Nb composite wires
T. Gu, O. Castelnau, S. Forest +4
Nanostructured and architectured copper niobium composite wires are excellent candidates for the generation of intense pulsed magnetic fields (>90T) as they combine both high stren…
Modulation and amplification of radiative far field heat transfer: Towards a simple radiative thermal transistor
Karl Joulain, Younès Ezzahri, Jérémie Drevillon +1
We show in this article that phase change materials (PCM) exhibiting a phase transition between a dielectric state and a metallic state are good candidates to perform modulation as…
