The high temperature oxidation behavior of magnesium (Mg) alloys containing neodymium (Nd) was investigated at low level concentrations (0.3 and 0.5wt.%). Continuous heating experiments carried out in dry air-flow revealed, interestingly, that the ignition temperature (T i ) is raised from 640 o C (of pure Mg) to up to 770 o C at 0.5wt.% Nd addition. No significant improvement was detected with 0.3wt.% Nd. The analyses of the surface indicate that the two alloys form different oxide morphologies when oxidized at 500 o C for 12h in air. Although a more dense oxide scale forms with 0.3wt.% Nd addition compared to pure Mg, the ignition results showed that the Nd addition below 0.5wt.% is not effective on the oxidation resistance. The presence of Nd 2 O 3 plays an indirect protective role delaying Mg evaporation and ignition.
