Abstract
Densification behavior of 316L stainless-steel powder under die pressing was studied The friction effects between the powder and the die wall under different die pressing modes were also investigated. The elastoplastic constitutive equations, based on the yield functions by Fleck and Gurson and by Shima and Oyane, were implemented into a finite element program to simulate die compaction processes. The friction coefficient between the powder and the die wall was determined from the relationship between the compaction pressure and the ejection pressure. Finite element calculations were compared with experimental data for densification and deformation of 316L stainless-steel powder under single and double action die pressing.
