摘要：
A modified thermodynamic model (T-m-model) for the impurity diffusion in groups V and VI metals is described, which takes into account nearest- (NN) and next-nearest (NNN) neighbour monovacancy jumps. The correlation factor f is separately calculated with the aid of a Monte Carlo simulation. The calculation of f bases on a nineteen-frequency model for combined NN and NNN jumps. The comparison of calculated and experimental diffusion coefficients reveals good agreement for several systems. On the other hand it becomes obvious that the T-m-model is not applicable to the diffusion of group VIII metals in metals of the groups V and VI.
