The diffusive behavior of O was studied at 932 to 1142C. The results could be described by:

α-phase:     D (cm2/s) = 7.78 x 10-1 exp[-48.6(kcal/mol)/RT]

β-phase:     D (cm2/s) = 3.30 x 102 exp[-58.8(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([1204] to [1206], [1226] to [1227], [1234] to [1237]) yield:

Al: Ln[Do] = 0.46E – 31.1 (R2 = 0.998); O: Ln[Do] = 0.28E – 11.8 (R2 = 0.77);

Ti: Ln[Do] = 0.25E – 17.1 (R2 = 0.85)
