Atomic clusters exiting in the Zr 65 Ti 10 Ni 25 metallic glass and primary phases generated during crystallization were studied by x-ray scattering and high-resolution transmission microscopy. An intrinsic correlation between the atomic clusters and the primary phases has been revealed. It is found that there are topological icosahedral short-range orders ͑ISROs͒ in the as-cast sample in addition to fcc-Zr 2 Ni-type chemical SROs. These topological ISRO and fcc-Zr 2 Ni-type chemical SRO can simultaneously quasicrystallize/crystallize into the corresponding nanoscaled icosahedral quasicrystalline phase ͑I-phase͒ and fcc-Zr 2 Ni crystal as primary products during crystallization. The synchronic precipitation of these two metastable phases can be understood in terms of their structural similarity between the fcc-Zr 2 Ni and I-phase in local atomic configuration. In comparison with fcc-Zr 2 Ni crystal, the I-phase has a smaller size and lower volume fraction due to its lower growth rate attributed to its more complex composition and higher structural symmetry. The competitive growth between these two phases results in the development of nanostructured materials in this alloy after annealing.

“…To enhance our understanding of the physical characteristics of these hybrids we investigated their SAXS profiles to deduce structural information concerning their primary particle aggregates/agglomerates. For this purpose we employed Porod, Guinier and Kratky approximation laws [21][22][23][24][25][26][27][28][29][30]. These laws are used to deduce relevant information on their scattering lengths, thermal fluctuation parameters, fractals nature, interfacial thicknesses and macro-conformations.…”

“…In particular, SAXS technique is frequently employed to extract structural information about the textural morphology, fractal nature and structural heterogeneity of multi-domain supramolecular and polymeric systems. This technique is successfully used in the structural analysis of a wide variety of materials with different interfacial forces including proteins, polymers, glasses, composites as well as colloidal dispersions [21][22][23][24][25][26][27][28].…”
