%X High pressure gas atomization experiments have been carried out with Al-Pb immiscible alloy. Powders containing fine Pb dispersions have been obtained. A model describing the microstructure evolution in a rapidly solidified atomized droplet was developed. The model takes into account of the common effects of the nucleation, the diffusional growth of the minority phase droplets, the collisions and coagulations between the minority phase droplets and spatial phase separation. The formation of the microstructure of the atomized droplets was calculated. It was demonstrated that the calculated results have a good coincidence with the experimental ones. The solidification process of the atomized A1-Pb alloy drop was discussed in details.
