| Abstract: | Much attention has already been paid to impurity elements in magnesium and its alloys. The existing forms of several impurity elements such as Fe,Cu,Ni and Si are introduced firstly. The influence of impurities on the microstructure,corrosion resistance and mechanical properties of magnesium alloys is summarized detailedly. In addition,several methods to improve the purity of magnesium alloys including high-purity raw materials,optimized melting technique and magnesium alloy melt purification are discussed. It is eventually pointed out that impurity reduction is a noteworthy research direction for developing high performance magnesium alloys. |
