• Immiscible alloys
• Immiscible gap
• Liquid-liquid phase separation

A numerical model has been developed to describe the microstructural evolution of Al-In immiscible alloys through the miscibility gap. The model considers the common action of nucleation, diffusible growth, Brownian collision and motion collision between the second phase droplets. The simulation results are dynamically visualized and show that the volume fraction, distribution and size of the second phase droplets satisfactorily agree with the experimental results. So the model can be used to predict the microstructural evolution of Al-In immiscible alloys during the cooling process.
