摘要： PROBLEM TO BE SOLVED: To provide a magnesium alloy having superior heat resistance and castability.
SOLUTION: The magnesium alloy comprises, when the whole magnesium alloy is defined as 100 mass%, by mass%, 6-10% Al, 2.2-8.0% Ca, 0.1-1.0% Si, 0.1-1.0% Sn, 0.05-1.0% Mn, and the balance Mg with unavoidable impurities while satisfying the expressions of 0.35≤b/(a+c+d)≤0.75 and 0.2≤(c+d)≤1.4 when the contents of Al, Ca, Si and Sn are defined as a, b, c and d respectively (where the unit is mass%). In the magnesium alloy, Al-Ca-Mg-based compounds are crystallized in grain boundaries among Mg crystals in a form of a network, thereby a slip between the grain boundaries and the movement of dislocation in the grain boundary at a high temperature are suppressed to improve the heat resistance. The fine Ca-Si-Sn-Mg-based compounds are also dispersively formed, which improves the heat resistance and simultaneously enhances the ductility to decrease a casting crack.
