Temperature dependence of migration features of self-interstitials in zirconium Project supported by the National Natural Science Foundation of China (Grant No. 91126001) and the National Magnetic Confinement Fusion Program of China (Grant No. 2013GB109002). |
(color online) Schematic graphs for the movements of interstitial atoms and LSIA. Grey spheres denote the atoms at normal hcp lattice sites at which their Wigner–Seitz cells contain one atom. Dots, for example site L1 in panel (a) and site L2 in panel (b), denote LSIAs at which two atoms (red spheres) fall in their Wigner–Seitz cells. The normal lattice sites nearest to an LSIA are LSIA candidates. |
