Design and experimental verification of an innovative steel–concrete composite beam

This paper deals with the design method and the experimental verification of a new type of steel–concrete composite beam under static and fatigue loading. The connection is an alternative solution for steel–concrete composite bridges suitable for prefabric ...

Damage to Steel Buildings Observed after the 2011 Tohoku-Oki Earthquake

Dimitrios Lignos

A joint U.S.-Japan reconnaissance team examined the damage to steel building structures caused by the 2011 Tohoku-oki earthquake. In the city of Sendai, where the peak horizontal ground acceleration exceeded 1 g, the majority of steel buildings performed w ...

Load dependence of oxidative wear in metal/ceramic tribocouples in fretting environment

Abhishek Tewari

For a large number of non-oxideceramic/metal as well as for non-oxide particulate reinforced composite/metal tribocouples,oxidative wear is reported to play a major role in the overall damage and material removal process.The designing of new materials with ...

Two strain-hardening mechanisms in nanocrystalline austenitic steel: An in situ synchrotron X-ray diffraction study

Helena Van Swygenhoven, Steven Van Petegem, Patrick Schloth, Michael Andreas Weisser

The mechanical behaviour of nanocrystalline austenitic steels with and without yttria particles was investigated using in situ synchrotron diffraction during tensile deformation. Two different strain-hardening regimes were found. The first regime can be as ...

Laminated Metal Composites by Infiltration

Andreas Mortensen, Andreas Rossoll, Jérôme Krebs, Arda Cetin, Alexandre Durussel

We show that steel-magnesium alloy laminated metal composites (LMCs) can be produced by gas pressure infiltration of a liquid magnesium alloy between layers of stacked dimpled steel sheets. Resulting LMCs are amenable to subsequent warm rolling. The LMCs a ...

Microstructure and mechanical properties of an ODS RAF steel fabricated by hot extrusion or hot isostatic pressing

Nadine Baluc, Zbigniew Oksiuta

Ingots of an oxide dispersion strengthened reduced activation ferritic steel with the Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) chemical composition (in wt.%) were synthesized by mechanical alloying of elemental powders with 0.3 wt.% Y2O3 particles in a planetary ball ...

Life Cycle Analysis of a Solar Tower Thermal Power Plant

Aurélie Kuenlin

In this present work, a life cycle assessment is realized on Solar Two, a test project of a solar tower thermal power plant. The aim of this study is to quantify the impacts on the environment associated with all the stages from cradle-to-grave (production ...

New S-N curves for details in bridges with steel truss tubular superstructure

Alain Nussbaumer

The promotion of tubular structures in bridge construction is a meaningful goal since these are aesthetic, lead to structurally efficient systems as well as sustainable ones. Good fatigue design of the tubular superstructure is a key factor to ensure safet ...

Studying the Formation of Ni3C from CO and Metallic Ni at T=265 degrees C in Situ Using Ni K-Edge X-ray Absorption Spectroscopy

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis, Alexander Wokaun

Metallic Ni nanopowder (Ni-0) was monitored during 23 h of carburization (2CO + 3Ni(0) - Ni3C + CO2, T = 265 degrees C) using Ni K-edge X-ray absorption spectroscopy. X-ray diffraction analysis made afterward at room temperature revealed 28 +/- 3% Ni3C amo ...

Micro-, meso- and macrostructures in replicated microcellular aluminium

Yves Conde

This thesis is focused on the properties of microcellular aluminium, produced by replication processing, at the micro, meso and macrostructural level. The replication process is based on the infiltration of a porous sodium chloride (NaCl) perform with molt ...
