Self-diffusion of 54Mn was studied by using the serial sectioning method at 620 to 1150C. The results were described by:

620-850C:     D (cm2/s) = 2.4 x 10-3 exp[-30.2(kcal/mol)/RT]

950-1150C:     D (cm2/s) = 5.6 x 10-3 exp[-33.0(kcal/mol)/RT]

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)
