Morphology of swift heavy ion tracks in metallic glasses

Morphology and annealing kinetics of ion tracks in minerals

“…Small angle X-ray scattering (SAXS) provides an alternative technique to study ion track damage as it measures density changes at the nanometre scale. We have recently demonstrated, that SAXS can provide previously unresolved details of the track structure in amorphous SiO 2 [14][15][16], metallic glasses, and natural apatite [17][18][19]. Using in situ and ex situ annealing experiments, we have demonstrated that SAXS is well suited for determining the annealing kinetics of ion tracks [17].…”

Structural modifications of swift-ion-bombarded metallic glasses studied by high-energy X-ray synchrotron radiation

“…It is known that ions produce tracks with a diameter of a few nanometers [19]. From the macroscopic point of view, swift heavy ions can introduce anisotropic plastic deformation in metallic glasses [5,6].…”

“…In amorphous materials, the ion tracks were observed on the surfaces using scanning probe microscopy [15,16]. Recently, small angle X-ray scattering (SAXS) was successfully applied to evaluate ex situ the size of the ion tracks in different amorphous materials [17][18][19]. Ion tracks were represented by cylinders of different electron density with respect to the matrix.…”

Effects of Heavy-Ions on Soft-Magnetic Metallic Glasses Studied by Diffraction of Synchrotron Radiation

“…Increased hardness and Young's modulus in the Ti 45 Cu 45 Zr 5 Ni 5 Sn 5 MG is accompanied by the shortening of atomic pairs [7]. The influence of swift (few MeV per nucleon) heavy-ion bombardment on the amorphous structure of binary and ternary Fe-B-based MGs and VITROPERM-type alloy has been investigated by means of small angle X-ray scattering (SAXS) and X-ray diffraction (SXD) of synchrotron radiation, respectively [8,9]. SAXS proved creation of * corresponding author; e-mail: stefan.michalik@diamond.ac.uk ion tracks of cylindrical shapes with radius about 5 to 10 nm.…”
