Atomistic mechanism of corrosion-induced grain boundary migration in NiCr alloys in molten FLiNaK
Sadia Khan, Hamdy Arkoub, Miaomiao Jin
Corrosion of Ni-Cr structural alloys in molten fluoride salts is a persistent material degradation problem, yet the atomistic role of grain boundaries in this process remains poorl…
Atomistic Mechanisms of Stress-Dependent Molten Salt Corrosion in NiCr Alloys
Hamdy Arkoub, Jia-Hong Ke, Miaomiao Jin
Ni-based structural alloys in molten salt environments often experience simultaneous mechanical loading and corrosive attack, yet the mechanisms governing stress-corrosion interact…
Chemical Short-Range Order Regulates Hydrogen Energetics and Hydrogen-Dislocation Interactions in CoNiV
Beihan Chen, Dalia Sayed Ahmed, Yang Yang +1
Chemical short-range order (CSRO) has emerged as a critical structural feature in concentrated alloys, yet its coupling with hydrogen remains an active discussion. Here, we develop…
Percolating Corrosion Pathways of Chemically Ordered NiCr Alloys in Molten Salts
Hamdy Arkoub, Jia-Hong Ke, Kaustubh Bawane +1
Recent experiments have shown that chemical ordering in NiCr alloys can significantly accelerate corrosion in molten salt environments. However, the underlying mechanisms remain po…
Surface Orientation-dependent Corrosion Behavior of NiCr Alloys in Molten FLiNaK Salt
Hamdy Arkoub, Daniel Flynn, Adri C. T. van Duin +1
The corrosion behavior of NiCr alloys in molten FLiNaK salt is governed by complex Cr-F chemical interactions, necessitating a fundamental understanding for enhancing alloy perform…
