Kanert, O.O.KanertGuenther, B.B.Guenther2022-03-022022-03-021981https://publica.fraunhofer.de/handle/publica/170419The diffusion of Al in a Cu- 3.8 at % Al alloy has been investigated by observing the rotating-frame nuclear magnetic relaxation time T1rho of 27Al as a function of temperature. It is shown that relaxation measurements of the solute atoms in a dilute alloy provide the correlation time of the diffusive motion of these atoms, if quadrupolar interactions form the main contribution to the relaxation time. From the correlation times the Al-diffusion coefficient in the alloy has been determined. (orig.)endiffusionFremddiffusionKernspinrelaxationLegierungNMRverdünnte Legierung620660671530journal article
