The local dynamics of dendritic sidearms during coarsening are studied by combining in-situ radiography observations with numerical and analytical models. A flat sample of a Ga-In alloy is partially solidified and then held isothermally in a vertical

The specific area of the solid-liquid interface of an assembly of dendrites is an important integral measure of the morphology of the microstructure forming during alloy solidification. It represents the inverse of a characteristic length scale and i

The formation of the grain structure in Al-10 wt%Cu alloy during directional solidification was investigated experimentally. The alloy composition was chosen because of its special feature that both the initial melt composition and the solidifying pr

In this minireview, we summarize experimental and numerical studies particularly concerned with applications of rotating magnetic fields (RMF) or travelling magnetic fields (TMF) to directional solidification of metal alloys. After introducing some f

The specific area of the solid-liquid interface is an important integral measure for the morphological evolution during solidification. It represents not only the inverse of a characteristic length scale of the microstructure, but it is also a key in

We study the free dendrite growth of a pure substance under the influence of a parallel flow, modulated in time using two different approaches, by means of two-dimensional phase-field simulations. In a previous work amplified side-branching was shown

The free dendrite growth in a pure substance, supposed to a parallel forced convection which is modulated in time, is studied using two-dimensional phase-field simulations. We show that the response of the tip velocity to the velocity pulses exhibits
