Abstract
The influence of Nd and Gd additions on the microstructure, hardness and oxidation of AM50 magnesium alloy was investigated. Nd and Gd formed Al 2Nd, Al2Gd, Al-Mn-Nd and Al-Mn-Gd intermetallics and reduced the amount of β-phase. Grain size and hardness did not change significantly with the addition of Nd or Gd. For all the alloys, surface degradation was negligible at temperatures below 370°C. However, at 410°C, severe oxidation was observed and hardness values decreased by ∼30% due to grain coarsening. At this temperature, the modified alloys revealed oxidation rates between ∼2.3 and 20 times smaller than the unmodified alloy. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
