Abstract: The diffusion growth and collision coagulation of the second phase droplets during liquid-liquid phase transformation are discussed. The synthetical mathematical model describing the droplets' coarsening process have been put forward. Computer simulation with Zn-Pb monotectic alloy showed that this model is in accordance with the practical situation.
