抄録

  In this work, the Mg17Al12 phase was successfully synthesized by the Bulk Mechanical Alloying (BMA) based on repeating compression and extrusion cycles in the metallic die. After 2000 cycles of compression and extrusion, nano-structural Mg17Al12 phase was obtained in bulk form.<br>   X-ray diffraction (XRD), scanning electron microscopy with energy dispersive X-ray (SEM-EDX) and differential scanning calorimetry (DSC) analyses were carried out for several mechanically milled powder mixtures. The qualitative and quantitative analysis of phase abundance, evolution of microstructure and distribution of particles size were studied.<br>   It was demonstrated that Mg17Al12 alloy is able to absorb a large amount of hydrogen, higher than 3 mass% of Hydrogen.<br>
