Influence of anisotropy on heterogeneous nucleation

Michel Rappaz, Aurèle Mariaux

Heterogeneous nucleation is governed by the interplay of interfacial energies between a substrate, a solid and a liquid. Although the intensity of these energies can strongly change with the orientation of the nucleus for anisotropic media, this parameter ...

Continuous hot-dip galvanization is a process during which steel sheets are coated with a layer of Zn-Al alloy to protect them against corrosion. As the name indicates, this is achieved by dipping the preheated sheet into a bath of molten alloy. The sheet ...

The anisotropy of the solid-liquid interfacial energy plays a key role during the formation of as-solidified microstructures. Using the xi-vector formalism of Cahn and Hoffman, this contribution presents the effect that anisotropy has on the equilibrium sh ...

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

Michel Rappaz, Jonathan Friedli, Aurèle Mariaux

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 ...

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

Michel Rappaz, Emmanuelle Boehm Courjault, Alain Jacot, Mario Alberto Salgado Ordorica, Aurèle Mariaux, 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 < ...

Hot-dip galvanized Zn-0.2wt%Al coatings on steel sheets exhibit a strong basal texture ({0001} parallel to the sheet plane). Part of this texture call be explained by the faster growth of < 10 (1) over bar0 > dendrites as compared with < 0001 >, granting b ...
