Summary:Nanostructured Al-25at.%Fe-5at.%Ni intermetallics were prepared directly by mechanical alloying (MA) in a high-energy planetary ball-mill. The phase transformations and structural changes occurring in the studied material during mechanical alloying were investigated by X-ray diffraction (XRD). Scanning electron microscopy (SEM) was employed to examine the morphology of the powders. Thermal behavior of the milled powders was examined by differential thermal analysis (DTA). The solid solutions of Fe (Al) and Ni (Fe) in the Al70Fe25Ni5 system are observed at the early milling stage. The solid solutions transforms into amorphous and disordered Al (Fe, Ni) phase. The last milling products in the Al70Fe25Ni5 system are Al3Ni2, AlFe3 and AlFe0.23Ni0.77 phases.
