Abstract Based on the population dynamic method a model has been developed to describe
the solidification process and the thermal histories of gas-atomized droplets. The model is coupled with the droplets' heat transfer controlling equation and the droplets'
motion controlling equation, and used in Cu-13.5%Sn (mass fraction) alloy. The effects of the droplet size, the initial gas
velocity, the superheat of the melt and the wetting angle between the primary phase and the catalyzing substrate for heterogeneous
nucleation on droplet solidification behaviors were discussed.
