“…Combining SAXS with simultaneously performed wide-angle X-ray scattering measurements, it was shown that the existence of the ion tracks enhances the recrystallization of the amorphous metallic alloys, consistent with a melt-quench process during ion track formation that is different from that operational during the production of the metal [60].…”

Keywords:Rutherford backscattering spectrometry Raman spectroscopy X-ray diffraction Small-angle X-ray scattering Positron annihilation spectroscopy Ion beam modification a b s t r a c t Understanding the mechanisms of damage formation in materials irradiated with energetic ions is essential for the field of ion-beam materials modification and engineering. Utilizing incident ions, electrons, photons, and positrons, various analysis techniques, including Rutherford backscattering spectrometry (RBS), electron RBS, Raman spectroscopy, high-resolution X-ray diffraction, small-angle X-ray scattering, and positron annihilation spectroscopy, are routinely used or gaining increasing attention in characterizing ion beam modified materials. The distinctive information, recent developments, and some perspectives in these techniques are reviewed. Applications of these techniques are discussed to demonstrate their unique ability for studying ion-solid interactions and the corresponding radiation effects in modified depths ranging from a few nm to a few tens of lm, and to provide information on electronic and atomic structure of the materials, defect configuration and concentration, as well as phase stability, amorphization and recrystallization processes. Such knowledge contributes to our fundamental understanding over a wide range of extreme conditions essential for enhancing material performance and also for design and synthesis of new materials to address a broad variety of future energy applications.

“…environment due to their wide super-cooled liquid region, relatively high crystallization temperature, and a lack of neutron activation element. The researchers carried out some studies about the irradiation-induced damage in Fe-based metallic glasses: Umakoshi et al used high energy electron to irradiate FeZrB metallic glass and discovered that α-Fe phase nanocrystalline formed after the irradiation [4]; Rodriguez et al observed recrystallization phenomenon in amorphous Fe80B20 ribbons during the high energy Au ion irradiation experiments [5]; Rizza et al explained the crystallization in the Fe-based metallic glasses after the irradiation of Pb ion with an energy of 5GeV by the relaxation of the high level of energy deposited in electronic excitations along the path of ions [6]; Kane et al found that after the electron irradiation, the width of the first coordination shell of Fe atoms decreased and the amorphous matrix was transforming to more ordered phase in metallic glass FeSiBNb [7]; Sun et al irradiated amorphous FeSiNbZrB ribbons with 5MeV Xe ions and discovered that after irradiation, the number of nanocrystalline increased with the increase of irradiation fluences, but the size of nanocrystalline saturated as the ion fluences increased [8]. As the potential candidates of irradiation resistant materials in the fusion reactors, Fe-based metallic glasses need to sustain the bombardment of thermal neutrons, hydrogen isotope particles, helium ash, sputtering impurity atoms and high heat load.…”

The changes in structure and surface morphology of metallic glasses Fe80Si7.43B12.57 and Fe68Zr7B25 before and after the irradiation of He ions with the energy of 300keV were investigated, and were compared with that of the tungsten. The results show that after the He 2+ irradiation, metallic glass Fe68Zr7B25 still maintained amorphous. While a small amount of metastable -Mn type phase nanocrystals formed in metallic glass Fe80Si7.43B12.57 at the fluence of 4×10 17 ions/cm 2 (19dpa). The nanocrystals transformed into α-Fe phase and tetragonal Fe2B phase as the fluence increased to 1×10 18 ions/cm 2 (47dpa). Then the new orthogonal Fe3B phase and -Mn type phase nanocrystals appeared when the fluence increased further, and the quantities of nanocrystals increased. Blisters and cracks appeared on the surface of tungsten under the irradiation fluence of 1×10 18 ions/cm 2 , however only when the fluence was up to 1.6×10 18 ions/cm 2 , could cracks and spalling appear on the surfaces of metallic glasses.
