Abstract
Fe powders were mechanically processed by ball milling. The average size of coherent diffraction domains and the average strain content were determined by X-ray diffraction. A mathematical model was developed to describe the microstructural refinement process as a function of the number of collisions and to estimate the amount of powder effectively processed at individual collisions. The density of dislocations was also estimated. The obtained values suggest that Fe powders can locally undergo extremely severe deformation conditions.
