The impurity diffusion of Mn was studied at 843 to 927K by using the serial sectioning method. Carrier-free 54Mn was obtained by using the photo-nuclear reaction, 56Fe(γ,pn)54Mn. It was found that the results could be described by:

D (cm2/s) = 3.17 x 102 exp[-51.7(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([562] to [565], [567] to [570], [573] to [577], [581] to [585], [592] to [599], [608] to [611], [623] to [626]) yield:

Au: Ln[Do] = 0.67E – 20.7 (R2 = 0.999); Co: Ln[Do] = 0.43E – 12 (R2 = 0.69);

Cu: Ln[Do] = 0.69E – 22.7 (R2 = 0.99); Fe: Ln[Do] = 0.56E – 20.5 (R2 = 0.996);

H: Ln[Do] = 0.63E – 9.45 (R2 = 0.96); Mn: Ln[Do] = 0.52E – 21.4 (R2 = 0.993);

Zn: Ln[Do] = 0.77E – 24 (R2 = 0.99)
