EBSD: a powerful microstructure analysis technique in the field of solidification

Michel Rappaz, Alain Jacot, Emmanuelle Anne Boehm Courjault, Frédéric Claude Denis Dreyer, Christoph Niederberger

This paper presents a few examples of the application of electron back-scatter diffraction (EBSD) to solidification problems. For directionally solidified Al-Zn samples, this technique could reveal the change in dendrite growth directions from < 100 > to < ...

PHASE FIELD MODELING OF EQUILIBRIUM SHAPES AND GROWTH MORPHOLOGIES IN Al-Zn ALLOYS

Michel Rappaz, Frédéric Claude Denis Dreyer, Jonathan Friedli

The anisotropy of the solid-liquid interfacial energy, gamma(sl), plays a key role in the accurate prediction of growth morphologies in metallic alloys. This interfacial energy anisotropy can vary duo to alloy composition, especially when that of the pure ...

Etude des morphologies de solidification dans les alliages aluminium-zinc

Frédéric Claude Denis Dreyer

Aluminum zinc alloys constitute an important class of wrought alloys, the so-called 7000 series, and are also widely used as anti-corrosion coatings of steel sheets. They are also interesting from a more fundamental point of view because zinc, a hexagonal ...

Growth directions in directionally solidified Al-Zn and Zn-Al alloys near eutectic composition

Michel Rappaz, Martin Rhême, Frédéric Claude Denis Dreyer

Growth directions and crystallographic orientations of solidification microstructures have been measured in Al-Zn alloy near the eutectic composition. Al dendrites in Al-92 wt.% Zn alloy were found to grow along the I 10) directions while Zn dendrites in A ...

Grain selection and texture evolution in directionally solidified Al-Zn alloys

Michel Rappaz, Frédéric Claude Denis Dreyer

In a recent contribution, we have reported that dendrites in the aluminum-zinc binary system can change their growth direction continuously from {100} to {110} as the concentration of zinc CZn increases from 5 to 90 wt pct.[1] This was interpreted as an in ...

Orientation selection in dendritic evolution

Michel Rappaz, Frédéric Claude Denis Dreyer

Computational and experimental demonstration of dendritic crystal growth direction and the morphologic diversity of the resulting dendritic structures are discussed. The primary dendrite growth directions can vary continuously between different crystallogr ...
