The thermally activated deformation behaviour of single-crystalline microcast aluminium wires

Andreas Mortensen, Léa Deillon, Suzanne Godelieve Alphonsine Verheyden

A microcasting process is used to produce high aspect ratio ( > 30) monocrystalline pure aluminium wires with a diameter between 14 and 115 mu m. The role of thermal activation in the plastic deformation of these microwires is measured by means of (single) ...

Laue microdiffraction characterisation of as-cast and tensile deformed Al microwires

Andreas Mortensen, Helena Van Swygenhoven, Léa Deillon, Steven Van Petegem, Suzanne Godelieve Alphonsine Verheyden

Single-crystalline cast aluminium microwires with a diameter near 15 are characterised by Laue microdiffraction. A microwire in the as-cast condition exhibits a misorientation below over a length of 500 . The measured density of geometrically necessary dis ...

The effect of size on the plastic deformation of annealed cast aluminium microwires

Andreas Mortensen, Léa Deillon, Suzanne Godelieve Alphonsine Verheyden

Monocrystalline, cast aluminium microwires of diameter (D) below 25 mu m free of micromilling artefacts are annealed under protective atmosphere. Annealing increases the flow stress of all tested microwires, by an amount that is found, in a Haasen plot of ...

Thermal Activation, Intermittency and Size Effects in the Plastic Deformation of Cast Aluminium Microwires

Suzanne Godelieve Alphonsine Verheyden

The microcasting process is a scaled-down investment casting process in which molten metal is pressure-infiltrated and directionally solidified in water-soluble moulds. It was previously developed to produce metallic microwires with a diameter (D) between ...

Cast aluminium single crystals cross the threshold from bulk to size-dependent stochastic plasticity

Andreas Mortensen, Csilla Mikó, Jérôme Krebs, William Curtin, Suzanne Godelieve Alphonsine Verheyden, Satish I Rao

Metals are known to exhibit mechanical behaviour at the nanoscale different to bulk samples. This transition typically initiates at the micrometre scale, yet existing techniques to produce micrometre-sized samples often introduce artefacts that can influen ...

Experimental determination of the permeability of engineering textiles: Benchmark II

Véronique Michaud, Benoît Louis, Eliazar Rodriguez Garcia, Suzanne Godelieve Alphonsine Verheyden

In this second international permeability benchmark, the in-plane permeability values of a carbon fabric were studied by twelve research groups worldwide. One participant also investigated the deformation of the tested carbon fabric. The aim of this work w ...
