초록
The magnesium-base AZ61 alloy was cast while adding 1% CaO powder into the melt. It was hot extruded, and oxidized at 550-650oC in air in order to study its microstructure and oxidation behavior. Initially added CaO powder reacted with Al in the melt to Al2Ca particles that aligned along the extrusion direction. The formed Al2Ca particles increased the oxidation resistance through forming the superficial CaO scale at the upper part of the thin MgO oxide scale.
