This investigation attempts to assess quantitatively
the influence of material and particulate characteristics upon
the compaction behaviour of metal powders. The effects have
been studied mainly by isostatic compact ion to eliminate the
effects of die-wall friction. A range of powders has been
studied having a wide variation in material properties.
The application of the accurate data to existing
pressure-density formulae resulted in only limited success.
This necessitated the formulation of new relationships which
were based upon stress-strain behaviour in solid metals. A
formula has been proposed which success~llly describes the
isostatic compact ion of metal powders to densities beyond the
stage of maximum packing.
