Onset of rod eutectic morphology in directional solidification

Résumé

Initial dynamics of morphological selection in a succinonitrile-(D) camphor organic transparent rod eutectic system is investigated experimentally using directional solidification with specimen thicknesses of 20 and 200 mm. The shape of the solid/liquid interface, the specimen thickness, the initial single-phase boundary thickness, and the grain boundaries are all observed to influence the onset of the eutectic morphology in a geometrically constrained system. Additionally, initiation of eutectic growth within a thin liquid layer at the specimen slide wall and lateral propagation of the array is observed, as suggested in a previous study by the present authors.
