, and the maximum solubility is 3.0%Zn, more than that of Mg-Zn binary system (2.1%Zn) when the α-Mg solid solution is in equilibrium with the liquid phase. However, the solubility of Al in the α-Mg phase...), and thus the isothermal section of the Mg-rich corner at 350 ℃ in the ternary system was constructed. There are three phases at this temperature in equilibrium with α-Mg solid solution, including......
