by ASTM. Meanwhile, the alloying elements, Cu and Fe, are not analyzed in detail here because their contents are very low in AM60 alloy (Table 1), and actually they are taken as inclusions. 3.1... with Fe. Therefore, a lowest content of Mn is required for improving corrosion resistance of Mg-Al-Mn alloy[12]. So, the content of Mn is limited to 1%. However, the formation of Al-Mn compound......
