Processing of Metal Powders 179 The nonuniformity of the pressure in the ﬁgure (on p. 493) is due to the frictional resistance at the die walls and within the powder particles throughout the compact. The pressure will drop away from the punch because these eﬀects are cumulative, and are similar to the pressure drop in a water-pumping system.
