Abstract

The amorphous structure of aluminum alloy doped with transition (Fe, Ni) and rare earth (La) metals crystallizes with the formation of a multiphase nanocrystalline composite under irradiation with fast 38-MeV 12C+3 ions at a fluence of Φ = 5 × 1016 particles/cm2. The microhardness of the irradiated amorphous–nanocrystalline composite is higher than that of the unirradiated amorphous alloy. No phase transformations are observed in the polycrystalline state. The morphology of phases slightly changes owing to partial dissolution and coagulation of intermetallic compounds.
