This research presents the analysis of microstructure, mechanical, and corrosion behavior of three Mg-Zn binary alloys, Mg-1Zn, Mg-3Zn, and Mg-5Zn. The result of metallography for as-Cast Mg-Zn alloys with different Zn content shows that the presence of Zn will cause grain refinement effect to the microstructure of Mg-Zn alloys and allows the formation of γ phase of Mg-Zn precipitation along the grain boundaries. The addition of Zn also significantly increases the mechanical properties of magnesium alloys corresponding to fine grain strengthening and second phase strengthening effect. Immersion test in Ringer’s solution show that the addition of Zn in magnesium alloys reduce its corrosion rate by improving magnesium alloys corrosion potential.
