Abstract
During directional solidification of thin layers (50 μm) of the transparent CBr4-C2Cl6 lamellar eutectic alloy, we observed tilt waves, a type of instability consisting in small domains of tilted lamellae moving transversely along the growth front. This instability is a way the system adjusts its wavelength after a small perturbation, without creating or destroying lamellae.Keywords
