In recent years, experiments and numerical simulations have shown that the anisotropy of solid-solid interphase boundaries plays a crucial role in the selection of growth directions in lamellar eutectics. We use two-dimensional phase-field simulations to study the influence of this anisotropy on the dynamics of the lamellar spacing. It is known that, for isotropic interfaces, the local spacing obeys a diffusion equation. The dependence of the spacing diffusion coefficient on type and strength of the anisotropy is determined. Preliminary three-dimensional simulations are carried out to investigate spacing homogenization and the lamella elimination instability in massive (three-dimensional) samples.
