Abstract

We report on small-angle x-ray scattering (SAXS) measurements of amorphous Fe₈₀B₂₀, Fe₈₅B₁₅, Fe ₈₁B₁₃₅Si₃₅C₂, and Fe ₄₀Ni₄₀B₂₀ metallic alloys irradiated with 11.1 MeV/u ¹³²Xe, ¹⁵²Sm, ¹⁹⁷Au, and 8.2 MeV/u ²³⁸U ions. SAXS experiments are nondestructive and give evidence for ion track formation including quantitative information about the size of the track radius. The measurements also indicate a cylindrical track structure with a sharp transition to the undamaged surrounding matrix material. Results are compared with calculations using an inelastic thermal spike model to deduce the critical energy loss for the track formation threshold. The damage recovery of ion tracks produced in Fe₈₀B₂₀ by 11.1 MeV/u ¹⁹⁷Au ions was studied by means of isochronal annealing yielding an activation energy of 0.4 ± 0.1eV.
