摘要	A model is developed to describe the microstructure evolution in a Cu-Co drop during cooling in the metastable miscibility gap in the liquid state. Rapid solidification experiments have been performed with CU84CO16 alloy in a drop tube. The kinetic details of the liquid-liquid phase transformation in the Cu-Co drops have been calculated. The results demonstrate that the microstructure development is dominated by the common action of the nucleation and the diffusional growth of the minority phase precipitates under rapid solidification conditions. The calculated size distribution of the Co precipitates in powders and their average radius as a function of cooling rate are compared with the experimental results. The agreement is satisfactory.
