Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Atomistic simulations of bicrystal samples containing a grain boundary are used to examine the effect of hydrogen atoms on the nucleation of intergranular cracks in Ni. Specifically, the theoretical strength is obtained by rigid separation of the two cryst ...
A new martensitic ODS alloy (nominal composition Fe-9Cr-1W-0.2Ti-0.3Y 2O3) has recently been developed at CEA Saclay to achieve the goals defined for GEN IV reactors. The aim of this paper is to present the main challenges involved in the manufacturing of ...
This paper presents experimental results on creep and relaxation of UHPFRC at early age (3–8 days), under low to high tensile stresses (1.2, 2.7, 5.4, and 8.1 MPa—estimated as 13, 30, 60, and 90% of the tensile strength, respectively) up to the strain hard ...
One central aim of nanotechnology is the creation and exploitation of nanostructured materials with pre-programmed architecture and properties. The fabrication of functional nanostructures relies on versatile protocols of synthetic chemistry enabling the p ...
Friction stir processing (FSP) is a solid state route with a capacity of preparing fine grained nanocomposites from metal sheets. In this work, we employed this process to finely distribute TiO2 nanoparticles throughout an Al-Mg alloy, aiming to enhance me ...
Dry, compression molded films of medical grade poly-L-lactide (PLLA) showed a marked reduction in tensile strength and strain after accelerated ageing in aqueous NaOH at 50 degrees C. accompanied by mass loss, surface erosion, increased hydrophilicity and, ...
Various thermo-mechanical treatments were applied to refine and homogenise grain size and improve mechanical properties of hot-isostatically pressed (HIP) 14%Cr ODS ferritic steel. The grain size was reduced, improving mechanical properties, tensile streng ...
The scope of this paper is to present the global mechanisms of soil desiccation, including drying shrinkage and cracking. The paper first reviews the basic processes that are beneath the word “desiccation”. Then the results of an experimental study of desi ...
Despite the fact that displacement-based methods are now frequently applied when assessing the seismic performance of unreinforced masonry (URM) structures, the displacement capacity of in-plane loaded URM piers is still estimated from empirical rather tha ...
This paper reports on low-temperature and hermetic thin-film indium bonding for wafer-level encapsulation and packaging of delicate and temperature sensitive devices. This indium-bonding technology enables bonding of surface materials commonly used in MEMS ...
