Powder forming (P/F) combines powder
metallurgy (P/M) and forming technology and thus
possess the advantages of both processes that result in
both stronger and yet more versatile products with
complicated geometry and arbitrary alloy compositions.
In this paper, a finite element method is used to
investigate the deformation behavior and density
variation of extrusion of porous metal. The influences
of the parameters such as reduction of area, die
semi-angle, initial relative density and friction factor on
the extrusion force, effective stress distribution, relative
density variation and inhomogeneous factor are also examined.
