Magnesium alloys are a strong candidate for various applications in automobile and aerospace industries due to their low density specific strength. Micro-alloying magnesium with zinc, yttrium, cerium enhances mechanical properties of through grain refinement precipitation hardening. In this work, critical review magnesium-based binary systems including Mg-Zn, Mg-Y, Mg-Ce, Zn-Y, Zn-Ce is present...
