The diffusion of implanted solutes in the α-phase was studied at 948 to 1073K by using nuclear reaction analysis. The measurements showed that the diffusion coefficients yielded a linear Arrhenius plot:

D (cm2/s) = 1.4 x 102 exp[-77.6(kcal/mol)/RT]

The parameters were typical of normal substitutional behavior.
