“…Irradiation effects in amorphous and crystalline sputter-deposited Mo-Ni were explored in [7], where it shown that ion bombardment of crystalline Mo-Ni at temperature <570 o K caused complete transformation to amorphous state, and that irradiation at elevated temperatures accelerated thermally activated processes. Amorphous-to-crystalline phase transformation by neutron irradiation in Fe 83 B 17 alloy was studied in [8]. A series of studies on irradiation effects in amorphous and crystalline Fe-based alloys and the corresponding irradiation-induced changes in density, ductility, and Curie temperature were also reported in [8].…”

The study revealed that loss of ductility in an amorphous Fe-alloy coating on a steel substrate composite structure was essentially prevented from occurring, following radiation with modest neutron doses of ~2 x 10 18 n/cm 2. At the higher neutron dose of ~2x10 19 , macroscopic stress-strain analysis showed that the amorphous Fe-alloy nanostructured coating, while still amorphous, experienced radiation-induced embrittlement, no longer offering protection against ductility loss in the coating-substrate composite structure. Neutron irradiation in a corrosive environment revealed exemplary oxidation/corrosion resistance of the amorphous Fe-alloy coating, which is attributed to the formation of the Fe 2 B phase in the coating. To establish the impact of elevated temperatures on the amorphous-to-crystalline transition in the amorphous Fe-alloy, electron microscopy was carried out which confirmed the radiation-induced suppression of crystallization in the amorphous Fe-alloy nanostructured coating.

“…In [8], irradiation effects in amorphous and crystalline sputter-deposited Mo-Ni coatings were investigated, where it was found that ion bombardment of crystalline Mo-Ni at temperature < 570 o K led to complete transformation into the amorphous state with irradiation at elevated temperatures accelerating thermally activated processes. In [9], neutron irradiation induced amorphous-to-crystalline phase transformation was studied in Fe 83 B 17 alloys, establishing radiation-induced changes in density, ductility, and Curie-Néel temperature.

Amorphous Fe-based nanostructured alloy coatings thermally sprayed on bcc steel substrate, were subjected to neutron irradiation doses up to 2 × 10 19 n/cm 2. It is shown that the interplay between embrittlement and recovery of ductility is governed by amorphous to crystallization transition and phase decomposition in which temperature and irradiation dose have reciprocal effects. Microscopic (X-ray diffraction) observations on the behavior of the amorphous Fe-based alloy are correlated with relevant macroscopically observed mechanical behavior. It is shown that amorphous Fe-based alloy coatings maintain and even enhance their amorphous structure with irradiation, exhibit radiation-induced restoration of thermally-induced embrittlement and finally exhibit resistance to ductility loss up to the fluence of 2 × 10 18 n/cm 2 and good thermal stability up to 350 o C. The latter is deduced from X-ray diffraction experiments of in-situ tensile strain application on the irradiated coating.
