Sažetak

Powder forming is particularly attractive because it allows the cost and material saving advantages of conventional powder metallurgy, as well as the high production rates and property enhancement of forming. Therefore, powder forming is now a viable commercial method for the fabrication of high-strength parts. This study applied finite element method to investigate deformation behaviour and density variation in extrusions of porous metal. Effects of parameters such as reduction of area, die semi-angle, initial relative density and friction factor on extrusion force, effective stress distribution, relative density variation and inhomogeneous factor are also examined.
