摘要: With the multiphase field method, the stability of lamellar basic state is investigated during the directional solidification of eutectic alloy CBr4--C2Cl6. A great number of lamellar patterns observed in experiments are simulated, and a stability diagram for lamellar pattern selections is presented. The simulated growth behaviours of these patterns are found to be qualitatively consistent with Karma \textit{et al}'s numerical calculations and experimental results. The formation of the primary instability is attributed to the destabilization of solute boundary layer.
