Abstract

Here, this 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 10¹⁸ n/cm². At the higher neutron dose of ~2 x 10¹⁹, 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 Fe₂B 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.

Fast Neutron Irradiation Embrittlement-ductilitization of an Iron-based Amorphous Alloy using In Situ Synchrotron X-ray Diffraction

Journal Article Simos, Nikolaos ; Zhong, H. ; Zhong, Zhong ; ... - International Journal of Metallurgy and Metal Physics

Amorphous Fe-based nanostructured alloy coatings thermally sprayed on bcc steel substrate, were subjected to neutron irradiation doses up to 2 × 10¹⁹ n/cm². 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 exhibitmore »« less

Small-angle neutron scattering analyses of phase separation processes in amorphous alloys

Journal Article Gerling, R ; Schimansky, F P ; Wagner, R - Nuclear Science and Engineering; (United States)

During thermal annealing, amorphous Fe{sub 40}Ni{sub 40}P{sub 20} becomes brittle via a two-step process at 220 and 300{degrees}C. The first step results from a loss of excess free volume. This embrittlement is reversible: During subsequent neutron irradiation, a swelling of the alloy is observed, which corresponds to an increase in excess volume and a complete restoration of the ductility. This paper discusses small-angle neutron scattering which reveals that the second step of embrittlement, during which the specimen remains fully amorphous, is induced by phase separation into regions enriched and depleted in phosphorus. If amorphous Fe{sub 40}Ni{sub 40}P{sub 20} is exposedmore »« less
Neutron irradiation effects on the structural, magnetic and mechanical properties of amorphous and nanocrystalline Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9}

Journal Article Skorvanek, I ; Gerling, R ; Graf, T ; ... - IEEE Transactions on Magnetics

The response of the structural, magnetic and mechanical properties of amorphous and nanocrystalline Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9} to radiation damage is investigated by means of Moessbauer spectroscopy, hysteresis loop measurements and by bending tests. The irradiation of the nanocrystalline as well as differently thermally treated amorphous samples is performed in the in-core reactor position. Moessbauer experiments reveal that neutron irradiation leads to partial re-amorphization in the investigated nanocrystalline alloys. For all samples it is found that the deterioration of the soft magnetic properties occurs predominantly in the higher fluence range (10{sup 18}--10{sup 19} n{sub th}{center_dot}cm{sup {minus}2}). However, thismore »« less

FY05 HPCRM Annual Report: High-Performance Corrosion-Resistant Iron-Based Amorphous Metal Coatings

Technical Report Farmer, J ; Choi, J ; Haslam, J ; ...

New corrosion-resistant, iron-based amorphous metals have been identified from published data or developed through combinatorial synthesis, and tested to determine their relative corrosion resistance. Many of these materials can be applied as coatings with advanced thermal spray technology. Two compositions have corrosion resistance superior to wrought nickel-based Alloy C-22 (UNS No. N06022) in some very aggressive environments, including concentrated calcium-chloride brines at elevated temperature. Two Fe-based amorphous metal formulations have been found that appear to have corrosion resistance comparable to, or better than that of Ni-based Alloy C-22, based on breakdown potential and corrosion rate.
