Abstract
The Gibbs free energy was calculated between phosphorus and the main elements in Al-Si-Cu alloys sampled as A390 to study the reaction process and give theoretical directions for the adding of phosphorus in industry. The results show that the elements such as aluminum, silicon, and copper have the capabilities to react with phosphorus according to the preference of Al, Cu, Si. As temperature increases, the reactions between phosphorus and the elements become more difficult. If aluminum is in existence, the phosphides of other elements will transform to aluminum phosphide.
