WebAlpha-Fe (BCC) is the equilibrium structure below 900 C. The FCC unit cell has more interstitial sites than BCC. The BCC unit cell has fewer atoms. At 900 C, the diffusion coefficient for an interstitial impurity atom in alpha-Fe (BCC) is greater than that for the same interstitial impurity in gamma-Fe (FCC). WebHere we show that superconductivity in Fe 1 + xTe 0.7 Se 0.3 is enhanced by topotactic deintercalation of the interstitial iron with iodine, demonstrating the competing roles of …
Diffusion of He Interstitials and He Clusters in α-Fe
Webpotentials for the Fe–Cr–He system, fitted to a set of specially performed density functional theory calculations. The obtained results show that the dissociation energies of the studied He-V clusters, as well as the migration energy of He interstitial, are not significantly affected in the alloy compared to pure Fe. WebMay 14, 2024 · A high concentration of interstitials leads to ordering/disordering phenomena and lattice distortions, thus influencing the steels’ bulk performance. The research team identified two components that influence the interstitial ordering. The first one results from the anharmonicity caused by the strain fields in the Fe lattice. lake mary seafood restaurants
