Abstract

In the present study, the effect of various alloying elements on controlling of iron content in magnesium alloys was investigated. A number of alloying elements including manganese, calcium, and yttrium were added separately and simultaneously to the melt then the iron content was determined. The effect of elements on iron removing was evaluated and compared. The results were interesting since it has changed the idea of considering manganese as the best to remove iron from the melt. Other elements would be a better candidate to improve the corrosion resistance of magnesium alloys, especially yttrium due to its double effect on iron removing and forming of a protective film to protect the matrix. This study would contribute effectively to a design of high-performance magnesium alloys in the future.
