Abstract

In this study, the effect of grain boundarry diffusion on the iron nuclei formation during wüstite reduction process was investigated. Combined with the measurement of width of the iron nucleation dominant zone from grain boundaries with time and a grain boundary diffusion model, the grain boundary diffusion coefficient of Fe2+ ion in wüstite at 1073K has been evaluated.
