Warm Die Compaction of High Density PM Components
By increasing the density of sintered steels, the attractive combination of both higher strength and higher ductility of the material is gained. One process route to achieve high density PM components is to use high performing lubricants in combination with heated tool die. The synergies of lubricant content, efficiency of the lubricant and tool die temperature are presented in this paper. Using the right combination of mix composition and compaction parameters is one of the keys to obtain higher density of PM components.
