Self-diffusion in magnesium single crystals - Shewmon - 1956 () Citation Context ... measured experimentally but can be estimated based on an excellent correlation between D and melting temperature in hcp metals. Diffusion coefficients for the hcp metals Cd [Wajda et al., 1955], Mg [=-=...
in fluorite-structured ceria, oxygen diffusion is fast, and in comparison, the cations are effectively immobile acting as a stable sublattice within which oxygen atoms can diffuse. Nevertheless, in spite of the lethargic cation migration in ceria, its impact cannot be disregarded as ...
(5). In the present work, the bulk diffusion coefficients measured in dedicated experiments on CoCrFeNi single crystals [57] are used. The experimental parameters and the determined triple products are listed in Table 1. Since the present experiments were focused on GB diffusion measurements, the...
