Both the theoretical analysis and experiments on Al-Si alloys have shown that a relationship between the surface tension and the modification of Al-Si alloys exists. A new method for the rapid prediction of the the modification level of Al-Si alloys by surface tension has been introduced. The quantity of the modifier is found to have the greatest effect, followed by the time of the modification and then the temperature.
