abstract = "The morphological stability of lamellar eutectic coupled growth is investigated by means of quantitative three-dimensional phase-field simulations, both for a generic eutectic alloy with a symmetric phase diagram and for the transparent organic alloy carbontetrabromide-hexachloroethane. The instabilities that limit stable steady-state growth at large spacings are identified and compared to the instabilities known in thin samples. For all alloys and compositions investigated, the first instability to occur is a zigzag instability, which can saturate or lead to the breakup of the lamellae into rods or labyrinth structures, depending on the initial spacing and the volume fractions.
