Özet:

In this study, the microstructural, mechanical, and corrosion properties of the alloys obtained by adding Al-15Ti and Al-15Sr master alloys to the Mg-5Sn alloy were investigated. Microstructural properties of the alloys were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and optical microscopy (OM). The mechanical properties of the alloys were analyzed by performing tensile tests, macrohardness tests, and nanoindentation tests. Corrosion behavior of both alloys was investigated by determining the corrosion rates with both electrochemical techniques and immersion techniques in Hanks Balanced Salt Solution (HBSS). When the microstructure results were examined, it was observed that minor Ti and Sr have a significant effect on reducing magnesium grain size, with Ti being more effective in grain refining. When compared to Al-15Sr, the addition of Al-15Ti to Mg-5Sn improves both mechanical and corrosion properties more effectively.
