It was found that the data for 63Ni diffusion could be described by:

0.42%Mn:     D (cm2/s) = 4.95 x 100 exp[-67.46(kcal/mol)/RT]

1.26%Mn:     D (cm2/s) = 3.64 x 100 exp[-66.83(kcal/mol)/RT]

4.60%Mn:     D (cm2/s) = 1.44 x 10-1 exp[-64.61(kcal/mol)/RT]

9.70%Mn:     D (cm2/s) = 1.32 x 10-1 exp[-63.90(kcal/mol)/RT]
