Erratum: Influence of the thickness of a nanometric copper interlayer on Au/dielectric thermal boundary conductance (vol 124, 105304, 2018)

Ludger Weber, Maïté Blank

AMER INST PHYSICS2019

Mechanical properties of replicated cellular Zn and Zn1.5Mg in uniaxial compression

Andreas Mortensen, Ludger Weber, Karel Lietaert

We present here a study of the mechanical behavior of cellular Zn and Zn1.5Mg with densities between 11.9 and 24.5%, produced by replication processing using NaCl as a spaceholder. Cellular Zn and Zn1.5Mg deform homogeneously during quasi-static compressio ...

Influence of the thickness of a nanometric copper interlayer on Au/dielectric thermal boundary conductance

Ludger Weber, Maïté Blank

The influence of the thickness of a thin (1.5-30 nm) copper layer on the thermal boundary conductance (TBC) at the interface between gold and silicon, sapphire and diamond, respectively, was studied using Time Domain Thermoreflectance. Overall, a monotonic ...

Development of a new family of phosphorous-free Pt-based bulk metallic glasses

Ludger Weber, Maïté Blank, Hamed Kazemi, Cyrill Werner Cattin

New BMGs exhibiting strong glass forming ability combined with high hardness have been developed based on the Pt-Si-B ternary system. The effects of partial substitution of platinum by transition metals of the group iron, cobalt, nickel, and copper, as wel ...

Effects of partial crystallization in Pt-Si-B-based bulk metallic glasses on glass transition and crystallization of the remaining amorphous matrix

Ludger Weber, Hamed Kazemi, Cyrill Werner Cattin, Gilles Hodel

The influence of partial crystallization on the evolution of the characteristic temperatures, i.e. of the glass transition and the onset of crystallization, the density, and the mechanical properties of the bulk metallic glass Pt(49.95)Si(6)AB(24)Ge(3)Cu(1 ...

Fluid flow through replicated microcellular materials in the Darcy-Forchheimer regime

Andreas Mortensen, Ludger Weber, David Ingram, Alexandros Athanasiou-Ioannou, Sandra Guardia

We extend here a “bottleneck” flow model derived earlier for incompressible fluids flowing under creeping flow conditions [Despois, J. and Mortensen, A: Acta Materialia 53 (2005) 1381] to flow regimes where inertial losses are no longer negligible, causing ...

Effect of Ca addition on interface formation in Al(Ca)/Al2O3 composites prepared by gas pressure assisted infiltration

Ludger Weber

The aim of the work is to study interface formation between Al2O3 particles and Al(Ca) matrix in dependence of Ca content. Aluminium matrix composites (AMC) subjected to investigation were prepared by gas pressure assisted infiltration of alumina beds with ...

Elsevier Sci Ltd2016

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 ...

Influence of a Nanometric Al2O3 Interlayer on the Thermal Conductance of an Al/(Si, Diamond) Interface

Christian Monachon, Ludger Weber

The effect of an Al2O3 interlayer on the thermal conductance of metal (Al)/non-metal (diamond and silicon) interfaces is investigated using Time Domain ThermoReflectance (TDTR). Interlayers between 1.7 and 20nm are deposited on oxygen-terminated diamond an ...

Wiley-Blackwell2015

Influence of the wetting angle on capillary forces in pressure infiltration

Andreas Mortensen, Ludger Weber, Alain Léger

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature press ...
