Material characterization of magnesium elektron ZRE1 alloy with Praseodymium (Pr) and Erbium (Er) additions [PDF]

, 2020
The application of magnesium (Mg) is limited due to its poor mechanical and microstructural properties. The additions of rare earth elements to the Mg-Zn-Zr alloys will result in a much better properties of Mg alloy.

Mechanical Alloying of Mg-Be.

Journal of the Japan Society of Powder and Powder Metallurgy, 2000
Mg-10mass%Be, Mg-20mass%Be, Mg-30mass%aBe and Mg-40mass%Be alloys were synthesized by mechanical alloying (MA) of elementary Mg and Be powders for 720 ks milling under 66 kPa argon gas atmosphere using by a planetary ball milling. In the case of Mg-10mass%Be, the big blocks occurred due to the joining of the MA powders. Others showed fine powders after
