Equilibrium vacancy concentration measurements in solid argon
… bulk and lattice expansion to determine equilibrium vacancy concentrations, has been applied to solid argon. The results indicate that vacancy concentrations do not exceed 0.02% even at the highest temperatures. Although the data obtained were not sufficiently precise to allow unique …

Equilibrium vacancy concentration measurements and thermal properties of solid krypton
… defects o at temperatures above 75 K. The equilibrium atomic vacancy concentration inferred from these measurements appears to be represented by n = exp[(2.0 ± 0.5) - (895 ± 1000K)/T]. The monovacancy formation enthalpy and entropy is discussed and compared with other existing theoretical …

Atomic scale diffusion in complex systems from first principles
… tolerant alloys. We accurately model the vacancy metastable states observed in HCP Zr and for the first time examine the effect of these states on solute transport. Our results show that Sn and Al diffuse via vacancy mediated mechanism while Cr, Fe, Be and Ni diffuse via the interstitial …

Investigating the sink efficiencies of interfaces under irradiation
… materials. Among all aspects, interface-vacancy interactions are an important building block to understand many classical structural-property relationships in polycrystals. Interfaces serve as sinks, sources or trap sites for vacancies, which facilitate creep, can drive interface …
