Preparation of Al-Fe-V-Si Nanocrystalline Powders by Double Mechanical Alloying

A new synthesis technique, namely double mechanical alloying (DMA), has been developed to prepare Al-Fe-V-Si nanocrystalline powders, and during the DMA, XRD result indicate that a transformation from α-Al 13 (Fe,V) 3 Si + fcc-Al phase to quasicrystalline + fcc-Al phase was observed.
