Abstract
The fluctuation-theory model used for calculating migration energies in fcc metals is extended to compute homovalent-impurity diffusions. Compressions of migrating and saddle-point atoms are also included. Calculated migration energies for self-diffusion agree with experimental values. Calculated homovalentimpurity migration energies are close to those of self-diffusion as expected. Binding energies are shown to be small in accord with recent experimental and theoretical estimates.
