Pure Mg, Mg-5wt%Ca, and Mg-5wt%Ca-1wt%Zn alloys were cast, and their high-temperature oxidation behavior was investigated to determine the roles of Ca and Zn in oxidation. Ca and Zn additions refined the microstructure by formation of Mg2
Ca and Ca2
, respectively, at grain boundaries. Ca increased the oxidation resistance by forming a..... More
