In this paper the influence of alloying elements (Si and Al) on the precipitation process of Mg₂Sn phase in Mg-Sn alloys is presented. X-ray diffraction analysis was used to determine the lattice parameters of α -Mg solid solution, the phases content and size of the Mg₂Sn precipitates. It was found that silicon causes the refinement of the precipitates of Mg₂Sn phase, however it does not result in a significant increase of hardness increment after ageing treatment at 250°C. The addition of aluminum has a positive effect on the hardness of Mg-7Sn-5Si alloy.
