The diffusive behavior of O was studied at 750 to 1130C. The results could be described by:

α-phase (750-870C):     D (cm2/s) = 1.6 x 101 exp[-52.0(kcal/g-atom)/RT]

β-phase (950-1130C):     D (cm2/s) = 4.5 x 10-1 exp[-36.0(kcal/g-atom)/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)
