The migration of 95Zr was studied at 1200 to 1518K. The diffusion data obeyed:

D (cm2/s) = 1.74 x 10-5 exp[-23.77(kcal/mol)/RT]

No appreciable enhancement of Zr diffusion rates was observed at Ag contents of up to 1.45at%. At higher concentrations, the diffusivity increased with increasing Ag content.
