“…For the mobility of Cr in bcc Mo two works [45,46] are considered. Mulyakaev et al [46] studied the isotope 51 Cr diffusion in single crystal bcc Mo samples for the temperature interval from 1273 up to 1423 K. This data was given the dominant weight in the assessment. The data of Borisov et al [45] were given a low weight due to the lack of experimental description.…”

An assessment of the diffusion mobility functions for diffusion in the bcc Cr-Fe-Mo system is presented. The optimization of the mobility parameters is performed by utilizing experimental diffusion data available in literature. New diffusion data for the Mo diffusion is produced by a diffusion couple experiment and is accounted for in the optimization. Agreement between calculated and measured diffusion coefficients is found. An M 6 C coarsening experiment is performed and the measured coarsening rate can be reproduced by diffusion calculation using the DICTRA software and the developed kinetic description. The mobility parameters are shown to have a strong influence on the calculated coarsening rate.
