The Influence of Yttrium Addition on The Corrosion Resistance and Tensile Strength of as-Cast Mg-Y Alloys

This study shows the effect of Yttrium addition (2-6 wt%) on the mechanical properties and the corrosion resistance of Mg-Y binary fabricated from sacrificial magnesium anode. The beneficial of Mg anode source was tremendous for magnesium alloy especially for corrosion resistance. Improvement of mechanical properties due to the addition of Yttrium was caused by grain refinement solid solution strengthening. Tensile strength increased with the...
