| Abstract | A numerical model describing the microstructure evolution under the common action of the nucleation, the diffusional growth, the collisions and coagulations of the minority phase droplets and the spatial separation of the two liquid phases has been developed. The microstructure development in an unidirectionally solidified Al-Pb alloy has been simulated by coupling the calculated temperature and concentration fields with the kinetic equation which controls the microstructure evolution. It is indicated that the liquid-liquid transformation region moves from the bottom to the top of the sample during cooling. The Marangoni migration and the Stokes movement of droplets may cause a decrease of the local number density of droplets and an increase of the local supersaturation. The repeated nucleation of minority phase droplets may, therefore, occur locally. |
