Vacancy defects study in Fe based alloys induced by irradiation under various conditions

Nitrogen diffusion in vacancy-rich ferrite and austenite, from first principles to applications

“…For example, it has been shown that DFT-calculated nitrogen solubility's in iron have closer agreement with experimental data when excess vacancies [3] are introduced to idealised lattices. Furthermore, common processes encountered in industry; such as irradiation [4,5], quenching [6], ball milling and shot peening [7]; lead to deformed lattices which further increase nitrogen-vacancy interactions. Thus, the diffusion of nitrogen is considered in both idealised and vacancy-rich BCC/FCC lattices.…”
