Assessments of diffusion mobility parameters are performed for the bcc Cr-V-Fe alloy systemby taking available literature data into account. The main focus is on the diffusion of V in thebcc phase where, in addition to all binaries, ternary interaction parameters are assessed. Anexperiment is performed in order to study the coarsening of V-rich MC carbide, where thediffusion of V is believed to be of major importance. The measured coarsening rate is comparedwith the rate calculated using DICTRA, and found to be in satisfactory agreement. Theaspects of coarsening experiments as a method to evaluate diffusion mobility data arediscussed.
