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.
Aluminum zinc alloys constitute an important class of wrought alloys, the so-called 7000 series, and are also widely used as anti-corrosion coatings of steel sheets. They are also interesting from a more fundamental point of view because zinc, a hexagonal ...
Typical operating conditions for mobile sensor systems, and in particular mobile robots, exhibit a wide range of mechanical disturbances due their ego-motion. Sensor systems mounted on these mobile platforms often suffer to varying degrees from these distu ...
The wetting of angular alumina particle preforms by Cu-Sn alloys is investigated by means of pressure infiltration experiments conducted at 1150 A degrees C, using a system enabling dynamic and precise measurements of the metal volume injected into the pre ...
The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...
The formation of feathery grains during semi-continuous casting of Al-alloys [1, 2] is an interesting problem from both practical and theoretical points of view. These structures are formed by a lamellar sequence of twinned and untwinned regions separated ...
Ferritic ODS steels containing 14 or 18 wt.% Cr are produced by mechanical alloying (MA), hot consolidation and cold working. This study focuses on the evolution of interstitials such as oxygen, nitrogen and carbon at each stage of the fabrication route by ...
Introduction: As part of the MicroArray Quality Control (MAQC)-II project, this analysis examines how the choice of univariate feature-selection methods and classification algorithms may influence the performance of genomic predictors under varying degrees ...
This thesis is an exploration of deformation and fracture properties of a novel two-phase α2 + γ Ti46Al8Ta (at.%) alloy featuring a "convoluted" microstructure, produced by partners within a European Union project named IMPRESS. Properties of this alloy ar ...
A phenomenological modelling approach has been developed for the description of die massive and lamellar microstructures which form in gamma-TiAl alloys at high and moderate cooling rates, respectively. The nucleation of both massive and lamellar gamma is ...

The formation of twinned dendrites (feathery grains) in binary Al-Zn, Al-Mg, Al-Cu and Al-Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G approximate to 100 K cm(-1), v approximate to 1 mm s(-1), ...
