... sections of the die cavity. When the compacting pressure increases, and powder movement is restricted, shearing of the compact in planes parallel to the punch axis can only be avoided by proper sequencing of punch motions. Nevertheless, significant density variations can occur at the transition from one...

.... The work described in Ref 74 provides a good example of the usefulness of physical modeling. In this work, densification behavior during the forging of ferrous-powder compacts was rationalized based on the deformation of wedge samples made from plasticine ( Fig. 38 ).
