It was found that the data for 1080 to 1400C could be described by:

D (cm2/s) = 4.68 x 10-3 exp[-7.62(kcal/g-atom)/RT]

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)
