    Abstract: 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.
