Microstructural changes of graphite irradiated with swift heavy ions
Several methods, such as electron microscopy, scanning tunnelling microscopy (STM), X-ray diffraction, and decoration technique can be used to observe radiation damage in materials. In this work, we report microstructural changes and defect clusters induced by swift heavy ions (SHI) on graphite surfaces, visualized by scanning electron microscopy (SEM). Our studies have been performed on fine-g...
متن کاملVickers microhardness measurement for AlCu alloy irradiated with swift heavy ions
Irradiation-induced hardening is an important phenomenon concerning the nuclear reactor safety, because it induces the embrittlement of reactor pressure vessel steels. This phenomenon, however, can also be applied for the modification of hardness of alloys. In the case of FeCu alloys, we have reported that GeV heavy-ion irradiation remarkably increases the hardness [1]. Volkov et al. have expla...
متن کاملDegradation of polyimide under the irradiation with swift heavy ions
This study concentrates on radiation-induced ageing effects of polymers planned as insulating materials in the rapidly cycling superconducting magnets presently being developed for the FAIR facility. Although beam control and minimization of beam losses will be a major issue, the exposure of insulating parts (e.g. polyimide, polyetherimide, and glassenforced epoxy-compounds) of various accelera...
متن کاملThermal annealing study of swift heavy-ion irradiated zirconia
Sintered samples of monoclinic zirconia (α-ZrO2) have been irradiated at room temperature with 6.0-GeV Pb ions in the electronic slowing down regime. X-ray diffraction (XRD) and micro-Raman spectroscopy measurements showed unambiguously that a transition to the ‘metastable’ tetragonal phase (β-ZrO2) occurred at a fluence of 6.5x10 cm for a large electronic stopping power value (≈ 32.5 MeV μm). ...
متن کاملStructural modification of swift heavy ion irradiated amorphous germanium layers
Swift heavy ion (SHI) irradiation of conventional glasses results in non-saturable plastic flow as a consequence of the ion hammering effect [1]. SHI irradiation of amorphous Si (a-Si) at non-perpendicular incidence also leads to unsaturated plastic flow, which shows a linear dependence on the ion fluence. The positive direction of flow suggests that a liquid phase with density similar to that ...
