Özet

A formulation is developed for obtaining diffusivities of hydrogen in f.c.c. metals from cluster calculations of activation energies. Results for palladium compare reasonably well with medium temperature experimental values. A theoretical diffusivity curve is also suggested for hydrogen in rhodium.
