%X An experiential nucleation model in solidification processes of the industrial alloys was established by introducing the experimental parameters. This model not only described nucleation rate of the alloys quantitatively, but also linked the nucleation rates with the final grain sizes. The surface area of effective catalysts per unit volume melt and the contact angle of effective catalysts in the melt in solidification processes were calculated with the model and the nucleation characteristic of the casting was analyzed. The model was also used to estimate the nucleation parameters of Al-7Si alloy and Al-7Si-0.55Mg alloy in the definite melting condition.
