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

Dealloying of Cu-Mg-Ca Alloys [PDF]
Metals, 2018 The chemical dealloying of Cu-Mg-Ca alloys in free corrosion conditions was investigated for different alloy compositions and different leaching solutions. For some of the precursor alloys, a continuous, pure fcc copper with nanoporous structure can be obtained by dealloying in 0.04 M H2SO4 solution.

Mg effect on the cryogenic temperature toughness of Al-Mg alloys
Materials & Design, 2022 In this study, the Mg and temperature effects on cryogenic impact toughness of Al-Mg alloys are investigated. Cryogenic Charpy impact tests are conducted for several Al-Mg alloys: AA5083 (=reference), Al-6 Mg, Al-8 Mg, and Al-8.5 Mg. The temperature range is – 196 ˚C to 100 ˚C.
