چکیده انگلیسی
The threshold displacement energies (Ed) of Fe and Cr atoms in Fe-Cr alloys with Cr contents ranging from 0% to 21% have been obtained with molecular dynamics (MD) method. The values of Ed have been calculated along the three high-symmetry crystallographic directions [0â¯0â¯1], [0â¯1â¯1] and [1â¯1â¯1], a slightly 2° tilt from these directions, and a high-index crystallographic directions [1â¯3â¯5]. The results showed that [0â¯1â¯1] crystallographic direction had the highest Ed among the three high-symmetry directions in each Cr content alloy. Fe-9Cr had higher weighted average Ed than the other Cr content alloys for both Fe and Cr PKA due to its statistically high Ed along the [0â¯1â¯1] crystallographic direction up to 44.3â¯eV. And the statistical analysis on the primary damage configuration demonstrated thatâ¯ã1â¯1â¯0ãFe-Fe dumbbells were the dominant defect structures after relaxation. These data can enrich the database of Ed in Fe-Cr alloys and have potential applications in guiding the optimization design of radiation-resistant RAFM steels.
