Al-10Si-Mg alloy have been used for die casting and additive manufacturing. In this study, solution-treated Al-10Si-Mg and Al-10Si alloys (mass％) were heat-treated at several temperatures and the linear dimensional changes arising from the heat-treatments were investigated. A theoretical model for calculating the linear dimensional change in Al-Si-Mg ternary alloys was proposed, and the theoretically and the experimentally determined linear dimensional changes were compared. It was found that the linear dimensional changes of Al-10Si-Mg and Al- 10Si alloys were almost the same. In both alloys, the linear dimensional changes increased with the decrease of the heat-treatment temperature. The linear dimensional changes of Al-10Si-Mg and Al-10Si alloys agreed well with the values estimated by the proposed theoretical model. [ABSTRACT FROM AUTHOR] |
