Fundamentals of diffusion in phase transformations
2012 (English)In: Phase Transformations in Steels, Elsevier, 2012, Vol. 1, 94-125 p.Chapter in book (Refereed)
An atomistic model in the lattice-fixed frame of reference is the basis for the present discussion of the fundamentals of diffusion. It is shown that cross terms appear when gradients of some composition variable are introduced. It is demonstrated that an equation describing the movement of Kirkendall markers must be included in the new set of flux equations when the frame of reference is changed. It is argued that one should store information of mobilities rather than diffusivities and one should make calculations of diffusion in the lattice-fixed frame.
