Microstructural study of Mg-Zn alloys prepared by mechanical alloying
Elemental powder mixtures of Mg (particle size < 500 π m) and Zn ( < 100 π m) have been subjected to mechanical alloying (MA) in a planetary ball mill in order to produce suitable hydrogen storage alloys. Milling parameters such as ball-to-powder mass ratio and milling time have been varied to secur...

| Sumario: | Elemental powder mixtures of Mg (particle size < 500 π m) and Zn ( < 100 π m) have been subjected to mechanical alloying (MA) in a planetary ball mill in order to produce suitable hydrogen storage alloys. Milling parameters such as ball-to-powder mass ratio and milling time have been varied to secure the production of homogeneous nanocrystalline Mg-Zn alloyed powders containing 5 and 10 wt.% Zn. Characterization of the alloys thus produced has been carried out by X-ray diffraction, scanning electron microscopy, elemental microanalysis and transmission electron microscopy. It is demonstrated that the mechanically alloyed powders are metastable Mg-Zn solid solutions with a nanocrystalline structure and a homogeneous composition after MA. |
