Influence of morphological instability on grain boundary trajectory during directional solidification
Supriyo Ghosh, Alain Karma, Mathis Plapp +3
The interplay between the diffusion-controlled dynamics of a solidification front and the trajectory of a grain boundary groove at the solid-liquid interface is studied by means of…
Weakly faceted cellular patterns versus growth-induced plastic deformation in thin-sample directional solidification of monoclinic biphenyl
Tamas Borzsonyi, Silvere Akamatsu, Gabriel Faivre
We present an experimental study of thin-sample directional solidification (T-DS) in impure biphenyl. The plate-like growth shape of the monoclinic biphenyl crystals includes two l…
Hexagonal eutectic solidification patterns operating near a marginal stability point
Mikael Perrut, Silvère Akamatsu, Sabine Bottin-Rousseau +1
We study the long-time dynamics of hexagonal directional-solidification patterns in bulk samples of a transparent eutectic alloy using an optical method which permits real-time obs…
An experimental method for the in-situ observation of eutectic growth patterns in bulk samples of transparent alloys
Sabine Bottin-Rousseau, Mikael Perrut, Christian Picard +2
We present an experimental method for the in-situ observation of directional-solidification fronts in bulk samples of transparent eutectic alloys. The growth front is observed obli…
Dynamics of a faceted nematic-smectic B front in thin-sample directional solidification
T. Borzsonyi, S. Akamatsu, G. Faivre
We present an experimental study of the directional-solidification patterns of a nematic - smectic B front. The chosen system is C_4H_9-(C_6H_{10})_2CN (in short, CCH4) in 12 μm-th…
