The Production of Rare Earth based Magnesium and Aluminium Alloys – A Review

Rare Earth (RE) elements can be used as alloying agents to improve properties such as strength, conductivity, and corrosion resistance of Al or Mg light metal (LM) alloys. The current route for producing Al/Mg-RE alloys is by melting Al or Mg with the required RE metal. However, the high price of RE metals makes the cost of the alloys expensive and, as a result limits, their application. Extensive studies have been conducted to find alternative …
