Abstract
Densification behavior of dissimilar material powder (copper and pure iron powder) under die compaction was investigated. Experimental data were obtained for copper and pure iron powder compacts with various volume ratios under die compaction. Dissimilar material powder was simultaneously compacted into a jointed cylindrical compact with different powder materials in inner and outer part, respectively. To simulate densification behavior of dissimilar material powder, elastoplastic constitutive equation proposed by Shima and Oyane was implemented into a finite element program (ABAQUS) under die compaction. Finite element results were compared with experimental data for densification, deformed geometry and density distribution of powder compacts under die compaction.
