Abstract High pressure gas atomization experiments were done with Al-Pb immiscible alloy. Powders with a Pb-rich shell on their surfaces were obtained. A model describing the microstructure evolution in Al-Pb atomized droplet was developed. The solidification process was calculated. The results indicate that the formation of the shell-type structure is due to the heterogeneous nucleation of the Pb-rich phase on the atomized drop surface.
