In hypoeutectic Al-Si alloys, modification treatment is performed to improve mechanical properties and improve shrinkage. However, the Sr / P ratio at the time of improvement has not been clarified. Therefore, in this report, thermal analysis was performed while varying P and Sr to clarify the influence of the Sr / P ratio on the modification treatment while observing the microstructures of the allys. As a result, it was revealed that the Sr/P ratio of modified alloy structures more or less agrees with the stoichiometric ratio of Sr3P2.
