| Abstract: | Mixtures of elemental aluminium and magnesium powders corresponding to Al70Mg30 and Al50Mg50 compositions have been mechanically alloyed. After milling, an extended solid solubility of magnesium in aluminium upto 18 at% in the case of Al70Mg30 and 45 at% for Al50Mg50 was observed. These materials typically nanostructural (grain size 2–10 nm) transform into equilibrium structure upon heating. The stability of these materials was investigated using thermal analysis. |
