Article Preview

In this paper, a modified slab analysis has been used to determine the pressure distribution in the cylindrical compaction of aluminum powder under rotating die compaction. The analytical results are discussed to explain the pressure distribution and the interaction of the various parameters. To predict the density distribution in a powder compact under an applied pressure with torsion, the pressure function is coupled with some form of a pressure density relationship. High relative density can be realized in powder compacts by the rotating die compaction in contrast to the conventional compaction. A numerical analysis, using the DEFORM3D simulation software, is also carried out on the compaction under the rotating punch.
