Abstract
The microstructure evolution during a liquid-liquid phase transformation was calculated. The effect of convections on the microstructure development was investigated. The results demonstrate that the convective flow against the solidification direction causes an increase in the local nucleation rate. Convections lead to a more nonuniform distribution of the minority phase droplets (MPDs) in the melt. They cause an increase in the size of the largest MPDs and are against the obtaining of the immiscible alloys with a well dispersed microstructure.
