High-Temperature Oxidation of AZ91D/Y2O3 Magnesium Composites in Air
The AZ91D magnesium composite containing 3 wt% Y2O3 was cast, and its oxidation behavior was investigated above 430 °C in atmospheric air. It consisted primarily of the α-Mg matrix grains and a small amount of Al12Mg17. Al and Mg in the alloy diffused into the initially added Y2O3 particles to form (Al, Y)O or to dissolve in Y2O3. Although Y2O3 increased the oxidation resistance, the composite still experienced rapid oxidation and burning above 450 °C, because non-protective MgO was the main oxide.
