Evaluation of dislocation density and interstitial carbon content in quenched and tempered steel by internal friction

In this work, mechanical spectroscopy (internal friction) is used for a qualitative evaluation of interstitial carbon content in martensite and of the dislocation density in bulk samples of quenched and tempered steel. On one hand, the decrease of the ampl ...

Fatigue behaviour prediction of steel reinforcement bars using an adapted Navarro and De Los Rios model

Alain Nussbaumer, Marina Rocha Pinto Portela Nunes

Fatigue cracks tend to initiate on the rebar surface and therefore, the surface conditions may control their fatigue behaviour. This study investigates the influence of surface microstructure and roughness dispersion on the scatter and fatigue life of hot ...

Thermal and damping behaviour of magnetic shape memory alloy composites

Véronique Michaud, Susanne Glock

Single crystals of ferromagnetic shape memory alloys (MSMA) exhibit magnetic field and stress induced strains via energy dissipating twinning. Embedding single crystalline MSMA particles into a polymer matrix could thus produce composites with enhanced ene ...

Factors affecting the strength of P{011}〈566〉-texture after annealing of a cold-rolled Al–Mn–Fe–Si alloy

Ke Huang

Elongated coarse P{011}-oriented grains are frequently observed after annealing of cold-rolled Al–Mn alloys with a highly supersaturated solid solution level. In this study, important factors affecting the strength of the P-texture component after ann ...

Early cluster formation during rapid cooling of an Al-Cu-Mg alloy: In situ small-angle X-ray scattering

Jean-Marie Drezet, Helena Van Swygenhoven, Patrick Schloth

The formation of Cu-Mg clusters in an Al-Cu-Mg aluminum alloy is observed by small-angle X-ray scattering during cooling. Cooling rates are choosen to mimic the different conditions obtained at the surface and in the center of large forgings. Clusters of 0 ...

Inkjet Printed SnO2 Gas Sensor on Plastic Substrate

Nico de Rooij, Danick Briand, El Hadji Malick Camara, Mathilde Rieu

We report on the development of a metal oxide (MOx) sensor prepared by inkjet printing technology onto polyimide foil. Gold electrodes and a gold heater were printed on each side of the substrate, respectively. SnO2 based ink was developed by sol-gel metho ...

Aging of asymmetric dynamics on the random energy model

Jean-Christophe Mourrat

We show aging of Glauber-type dynamics on the random energy model, inthe sense that we obtain the annealed scaling limits of the clock process and of theage process. The latter encodes the Gibbs weight of the configuration occupied by thedynamics. Both lim ...

Fabrication of complex oxide microstructures by combinatorial chemical beam vapour deposition through stencil masks

Paul Muralt, Andreea Veronica Savu, Silviu Cosmin Sandu, Estelle Wagner, Scott Harada, Giacomo Benvenuti

Chemical Beam Vapour Deposition is a gas phase deposition technique, operated under high vacuum conditions, in which evaporated chemical precursors are thermally decomposed on heated substrates to form a film. In the particular equipment used in this work, ...

Isothermal and Non-Isothermal Annealing of Cold-Rolled Al-Mn-Fe-Si Alloys with Different Microchemistry States

Ke Huang

Investigation of the microstructural evolution of Al-Mn-Fe-Si alloys during annealing after cold rolling has been carried out. The effect of microchemistry state in terms of Mn in solid solution, constituents, size and volume fraction of dispersoids, intro ...

Correlation between ferrite grain size, microstructure and tensile properties of 0.17wt% carbon steel with traces of microalloying elements

Shankha Nag

Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
