Replicated microcellular aluminium structures for thermal management

Open-pore aluminium foams are of interest in thermal management of power electronics due to their large specific surface area, low weight and relatively high thermal conductivity. The replication process is a low-cost and simple foam manufacturing method t ...

Surface Reaction Barriometry: Methane Dissociation on Flat and Stepped Transition-Metal Surfaces

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick, Francesco Nattino

Accurately simulating heterogeneously catalyzed reactions requires reliable barriers for molecules reacting at defects on metal surfaces, such as steps. However, first- principles methods capable of computing these barriers to chemical accuracy have yet to ...

Heat expandable biopolymers for one-step production of foam core sandwich composites

Yonghoon Yoon

The overall aim of this work has been to develop sustainable solid thermally activated foam precursors suitable for the in-line production of lightweight bio-based foam core sandwich structures with consolidated wood particle facings, using a non-inflammab ...

Measuring the accuracy of softball impact simulations

Pascal Fua

A study has been conducted to review viscoelastic and foam-constitutive models to describe sport ball response to impact with a rigid cylindrical surface. The impact model was developed to simulate a ball-bat collision. Comparisons were made to actual impa ...

Multi-scale modeling of elasto-plastic response of SnAgCu lead-free solder alloys at different ageing conditions: Effect of microstructure evolution, particle size effects and interfacial failure

John Botsis, Joël Cugnoni, Milad Maleki

In microelectronics applications, SnAgCu lead-free solder joints play the important role of ensuring both the mechanical and electrical integrity of the components. In such applications, the SnAgCu joints are subjected to elevated homologous temperatures f ...

Effect of hydrostatic pressure on flow and deformation in highly reinforced particulate composites

Andreas Mortensen, Ludger Weber, Maria Gabriella Tarantino

Infiltrated particle reinforced composites combine a dense matrix with particles that are in mutual contact and can therefore transfer compressive stress directly from one particle to the next. As a result, these composites may combine characteristics of t ...

Microstructure and tensile properties of ODS ferritic steels mechanically alloyed with Fe 2 Y

Philippe Spätig, Nadine Baluc

An oxide dispersion strengthened ODS ferritic steel has been produced by mechanical alloying of Fe–14Cr–2W–0.2Ti (wt.%) prealloyed powder with 0.55 (wt.%) Fe2Y intermetallic particles and consolidated by hot isostatic pressing. The microstructure after the ...

Reactive friction stir processing of AA 5052-TiO2 nanocomposite: process-microstructure-mechanical characteristics

Friction stir processing (FSP) is a solid state route with a capacity of preparing fine grained nanocomposites from metal sheets. In this work, we employed this process to finely distribute TiO2 nanoparticles throughout an Al-Mg alloy, aiming to enhance me ...

Influence of processing routes on morphology and low strain stiffness of polymer/nanofibrillated cellulose composites

Yves Leterrier, Pierre-Etienne Bourban, John Christopher Plummer, Sylvain Cyril Claude Galland, Lars Berglund

The morphology of polymer/nanofibrillated cellulose (NFC) composite sheets produced using different techniques and its influence on low strain stiffness were assessed by optical and transmission electron microscopy. Solvent processing led to relatively hom ...
