Experimental and numerical study of microstructure formation and the origin of crystallographic misorientation in Al-Zn-Si alloy coatings
Al-Zn-Si alloy coatings are widely used for the corrosion protection of steel sheets. In addition to the favorable corrosion properties, the Al-43wt%Zn-1.6wt%Si coatings present several features which are of metallurgical interest. The first one is their s ...
EPFL2007Footprints of deformation mechanisms during in-situ x-ray diffraction
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 ...
EPFL2006Temperature dependence of lattice mismatch and gamma' volume fraction of a fourth-generation monocrystalline nickel-based superalloy
The strain distribution in a new generation nickel-based single crystal superalloy has been determined in the temperature range 293K–1598K. Measurements have been performed using diffraction of high energy synchrotron radiation (150keV, λ = 0.008 nm) to de ...
2006The relationship between the irradiation induced damage and the mechanical properties of single crystal Ni
Irradiation is known to lead to a degradation of the mechanical properties of materials. This is particularly crucial in the case of materials that will be used in the future thermonuclear fusion reactor, where extremely high irradiation doses are expected ...
EPFL2005Effects of neutron irradiation on the microstructure and mechanical properties of the heat affected zone of stainless steel welds
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, ...
EPFL2005Plastic flow of martensitic model alloys
Philippe Spätig, Robin Schäublin, Raul Alejandro Bonadé
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 ...
2004High temperature deformation mechanisms of cemented carbides and cermets
The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...
EPFL2004High-strain response of piezoresistive thick-film resistors on titanium alloy substrates
Peter Ryser, Thomas Maeder, Caroline Jacq
We examine, in this work, the integration and high-strain response of piezoresistive thick-film resistors on titanium and titanium alloy, as compared with ferritic stainless steel and the standard alumina substrates. In general, titanium and its alloys are ...
2004Microstructural analysis of i-AlPdMn quasi-crystals deformed between room temperature and 300 degrees C under confining pressure
AlPdMn quasi-crystalline specimens were deformed at low temperatures using a high-confining-pressure device. The microstructures, observed in each sample by transmission electron microscopy, depend on the deformation temperature and show that plastic defor ...
2003Post-irradiation deformation in a Fe-9%Cr alloy
The deformed microstructures of both irradiated and unirradiated Fe-9%Cr (Fe-9Cr) uniaxial tensile specimens have been examined to identify controlling mechanisms. Deformation following irradiation is found to occur in poorly defined channels about 100 nm ...
