Microstructure evolution and corrosion properties of Mg-2Dy-0.5Zn （at.%） alloy during cooling after solution treatment were investigated. The microstructure of alloy in the solid solution state （530 oC, 12 h） was composed ofα-Mg and small amounts of （Mg, Zn）xDy phases. During cooling at a cooling ra...
