Process Mechanics and Surface Integrity Induced by Dry and Cryogenic Machining of AZ31B-O Magnesium Alloy [PDF]

, 2013
The corrosion resistance of magnesium alloys depends mainly on its surface integrity. Previous experimental studies have shown that machining can induces small (nano-scale) grain size, compressive residual stresses and basal plane crystallographic ...

Spinodal decomposition and radiation damage of a FeCuMnNi high-entropy alloy

Nuclear Materials and Energy, 2023
The precipitation of Cu-rich phases during the irradiation process will reduce radiation resistance in Fe-Cu-Mn-Ni reactor pressure vessel steels. Therefore, high-entropy alloys with excellent radiation resistance are expected to replace reactor pressure

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

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.
