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.

The best linear fits to the solute diffusion data ([1305] to [1309], [1313] to [1314], [1317] to [1318], [1322] to [1325], [1332] to [1334]) yield:

Cr: Ln[Do] = 0.55E – 22.7 (R2 = 0.82); H: Ln[Do] = 0.17E – 8.2 (R2 = 0.32);

Mn: Ln[Do] = 0.27E – 14 (R2 = 0.97); O: Ln[Do] = 0.29E – 14.4 (R2 = 0.37);

Zr: Ln[Do] = 0.34E – 18.9 (R2 = 0.999)
