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.
The effects of neutron irradiation on austenitic stainless steels, usually used for the manufacturing of internal elements of nuclear reactors (e.g. the core shrouds), are the alteration of the microchemistry and the microstructure, and, as a consequence, ...
Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...
An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
Nanocrystalline metals have been an area of great interest in recent years due to their enhanced characteristics. One of the most striking is implied by the Hall-Petch relation: with decreasing grain size the material becomes stronger. This promise is fulf ...
Nuclear materials have been successfully employed in commercial fission reactors for many decades. Research and material development for advanced fission system and future thermo-nuclear fusion reactors have acquired maturity while great challenges remain ...
The present work deals with the determination of mechanical properties of materials using instrumented indentation techniques. The main advantage of indentation testing is that it is relatively simple to perform and does not need any special and time-consu ...
During nanoindentation measurements of thin films the formation of cracks within the film as well as of pile-up or sink-in around the indent are known to affect significantly the precision of hardness and Young's modulus values. The crack pattern in brittl ...
At early age, ultra high performance fibre reinforced concretes (UHPFRC)undergo significant volumes changes (thermal deformation and autogenous shrinkage)related to their composition. These deformations can be restrained by different elements respective to ...
This work is focussed on a high carbon tool steel used for the production of files. The mechanical properties of the files depend on a hardening thermal treatment that produces a martensitic structure. Thus, the motivation for this work is technological: w ...
This thesis explores the processing and properties of microcellular aluminium-based materials produced by replication. It includes the development of a pressure infiltration process for net-shape component production, structural characterization of the foa ...
