Finite differential method was adopted to solve the model. The average lamellar spacing of the Al Al 3Fe eutectic alloy and the content fields ahead of the solidifying interface under different growth rates were calculated. Directional solidification experiments were carried out in order to prove the modification of the modeling. The experimental results are in relatively good agreement with the calculations.展开更多
