Thermoelectric magnetohydrodynamics in dendritic solidification
… currents that are naturally inherent to solidification processes will interact with this magnetic field, resulting in a Lorentz force. This force will exist in a microscopic region in the vicinity of the solidification front, generating microscopic fluid flow in the liquid region which …

Parallel Lattice Boltzmann Method for Convection in Dendritic Solidification
… flow in multi-physics problems, such as alloy solidification, focusing on the effects on microstructure evolution. The literature has shown the importance of fluid flow in solidification as it affects the morphology and evolution of the growing dendrites. Because solute flow represents the most …

Learning two-dimensional spatial dynamics from experimental data
… The goal is to model experimental data, the dendritic solidification of ammonium bromide crystals, using a learning algorithm to search through a space of possible models in order to find an optimal description of the data. The space of possible models is a class of probabilistic cellular …

On the length-scale and location of channel nucleation in directional solidification
… density layer that exists ahead of the moving solidification front. With D the diffusion coefficient in the melt and V the solidification rate, the thickness of this layer, and therefore the stability of the systems studied, is shown to be a function of the length scale D/ V, where it is shown …

Near-congruent solidification of castings
… point result in a completely cellular (non-dendritic) solidification morphology for a composition range ~3 wt % Mn about the congruent composition (C<sub> c</sub>). The degree of cellular solidification was found to depend on the mold material. Increased mold conductivity lead to a narrower …

The influence of core crystallization and mantle overturn on ancient dynamos
… early history. We find that cumulate inner core solidification would be capable of sustaining a dynamo during the bulk of solidification, but that there may be insufficient power for a dynamo in an inward dendritic solidification scenario. Next, we explore the origin of the magnetic field …

Numerical simulation of dendritic growth of binary alloys
… finite element model for simulation of dendritic solidification of binary alloys is developed. The model solves the coupled time-dependent temperature and solute concentration equations on two independent meshes: a fixed mesh for the temperature and an adaptive interface-conforming mesh …

Surface modification of ceramic and metallic alloy substrates by laser raster-scanning
… over 3D carbon–carbon composites cylinders (c) dendritic solidification structures of Mar–M 247 confined powder precursor grown from polycrystalline Alloy 718 substrates. A heat transfer model was developed to illustrate that the aspect ratio of the laser scanned pattern and the density of …

Beiträge zur röntgenradioskopischen Visualisierung und Charakterisierung von Erstarrungsvorgängen und zweiphasigen Strömungsphänomenen in metallischen Schmelzen
Röntgenradioskopische Bildgebungsverfahren ermöglichen es, ein besseres Verständnis der zweiphasigen Strömungsphänomene und der Prozesse der Mikrostrukturentstehung während der Erstarrung in Metallschmelzen intuitiv zu gewinnen, da diese Verfahren die innere Gestalt der sonst undurchsichtigen …
