Modification of Fe-B based metallic glasses using swift heavy ions
Abstract
<p>We report on small-angle x-ray scattering (SAXS) measurements of amorphous Fe<sub>80</sub>B<sub>20</sub>, Fe<sub>85</sub>B<sub>15</sub>, Fe <sub>81</sub>B<sub>135</sub>Si<sub>35</sub>C<sub>2</sub>, and Fe <sub>40</sub>Ni<sub>40</sub>B<sub>20</sub> metallic alloys irradiated with 11.1 MeV/u <sup>132</sup>Xe, <sup>152</sup>Sm, <sup>197</sup>Au, and 8.2 MeV/u <sup>238</sup>U 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 Fe<sub>80</sub>B<sub>20</sub> by 11.1 MeV/u <sup>197</sup>Au ions was studied by means of isochronal annealing yielding an activation energy of 0.4 ± 0.1eV.</p>
