Abstract: Solidification experiments have been done with Zn-Pb alloy under the simulant microgravity condition of orthogonal electric and magnetic fields. Computer simulation has been carried out for the processes of the coarsening of the dispersion droplets and the formation of the gravity segregation during cooling this kind of alloy in their liquid-liquid temperature regions. Experiments and analyses show that electric and magnetic fields properly selected can decrease the coarsening rate of dispersion droplets greatly and slow down the velocity at which the gravity segregation is formed.
