The diffusivity of 51Cr was determined by using serial sectioning methods. The data for 1201 to 1479K could be described by:

D (cm2/s) = 4.53 x 10-3 exp[-32.8(kcal/mol)/RT]

It was deduced that the correlation factors were negative, and it was suggested that interstitial/vacancy pairs and ω-phase embryos might be rate-controlling.

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)
