Abstract
With the aid of the theory of irreversible processes the author has succeeded in deriving relationships between the intrinsic diffusion coefficient, the tracer diffusion coefficient, and the correlation factor for a jump of single vacancies in closely packed alloys of the substitution type. The derived relations include those obtained by Manning (1967). For very dilute or infinitely dilute solutions the thermodynamic factor, the ratio of the intrinsic diffusion coefficients, the jump frequency relationships and the correlation factor of the impurity can be calculated from experimentally determined diffusion data.
