High voltage consolidation of carbonyl iron powder has been studied. The high voltage consolidation process occurs at a constant speed of the punches until they stop. The experimental dependence of the height of consolidated cylindrical specimens has been determined for different values motion of punches. The porosity distribution in the volume of consolidated samples was studied. Porosity gradient was formed in the consolidated material due to wave compaction of the powder sample. Computer simulation of iron powder compaction during high-voltage consolidation is considered on the basis of differential equations expressing the laws of conservation of mass and momentum. The numerical results of computer simulation are in good agreement with the experimental values of the porosity distribution in the consolidated carbonyl iron samples.
