Abstract Rapid directional solidification experiments were carried out with Al-Pb alloy. The microstructure evolution during the solidification was calculated according to the practical experimental conditions. The results indicate that, under a constant solidification velocity, the size and its distribution width of the minority phase droplets increases with the Pb content of the alloy. For an alloy of given composition, the size and its distribution width of the minority phase droplets decreases with the solidification velocity. The numerical results, which have an acceptable coincidence with the experimental ones, show the microstructure evolution process clear.
