Abstract

The laws of densification of difficultly deformable powders in the process of vibrational compaction were studied. It was found that the efficiency of the process depends upon the magnitude of the applied force necessary to density the powder. The necessary force is attained by rapid deceleration of the powder mass against the upper punch. Theoretical results were in good agreement with experimcntal data obtained on the unit ÉRGUK.
