Reduction / Oxidation Behaviour of Rare Earth Oxide - Light Metal Alloys

<p dir="ltr">One promising group of alloying elements is Rare Earth (RE) elements, which can improve the properties of Al and Mg alloys. An alternative and potentially more cost-effective approach to produce Al-RE or Mg-RE alloy is by metallothermic reduction of RE oxides using Al or Mg as the reductant. In this study, the reduction of RE oxide by Al and Mg were studied by employing thermodynamic calculations and high temperature experiment. The results from this study revealed the reaction mechanism as well as the kinetics of the reaction involves, which could help reduce the alloy cost and expand the alloy applications.</p>
