EBSD, SEM and FIB characterisation of subsurface deformation during tribocorrosion of stainless steel in sulphuric acid

Marco Cantoni, Stefano Mischler, Emmanuelle Boehm Courjault

The tribocorrosion behaviour of a 304L stainless steel/alumina contact was investigated in sulphuric acid at two imposed potentials (cathodic and passive) The metal deformation below the surface was investigated by analyzing cross sections using secondary ...

Elastomer Composites for Actuator Applications

Martin Molberg

Dielectric elastomers are highly promising as functional materials for the rapidly developing field of flexible actuator and generator technology. They offer a unique combination of low densities and large reversible deformations of up to more than 100% in ...

ALT-evaluation of high stiffness base layers with high percentages of reclaimed asphalt

Nicolas Bueche

New Road Construction Concepts (NR2C) is a FEHRL-project supported by the European Commission under the Sixth Framework Programme. NR2C develops perspectives and specific innovations, so that long-term visions are linked to short-term action. One of the id ...

Shape memory alloys for microsystems: A review from a material research perspective

Yves Bellouard

One important challenge of microsystems design is the implementation of miniaturized actuation principles efficient at the micro-scale. Shape memory alloys (SMAs) have early on been considered as a potential solution to this problem as these materials offe ...

2008

Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...

EPFL2007

On-column conductivity detection in capillary-chip electrophoresis was achieved by actively coupling the high electric field with two sensing electrodes connected to the main capillary channel through two side detection channels. The principle of this conc ...

Footprints 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 ...

Plastic deformation mechanisms in nanocrystalline columnar grain structures

William Curtin

We present an atomistic study of the plastic deformation mechanisms occurring in columnar structures of nanocrystalline Ni, with particular emphasis on the process of dislocation emission form the grain boundaries. The samples are constructed with grain bo ...
