The diffusivities of H and D at 110 to 165K could be described by:

D:      D (cm2/s) = 8.8 x 10-4 exp[-0.395(eV)/kT]

H:      D (cm2/s) = 1.1 x 10-4 exp[-0.350(eV)/kT]

The best linear fits to the solute diffusion data ([1063] to [1068], [1076] to [1078], [1080] to [1105], [1114] to [1117], [1120] to [1123]) yield:

Cu: Ln[Do] = 0.37E – 22.7 (R2 = 0.98); Fe: Ln[Do] = 0.33E – 21.4 (R2 = 0.998);

H: Ln[Do] = 0.66E – 11.5 (R2 = 0.46); Ni: Ln[Do] = 0.47E – 31.8 (R2 = 0.999);

O: Ln[Do] = 0.38E – 18.4 (R2 = 0.75)
