| Abstract Scope |
Die compaction of powders finds use in numerous fields ranging from powder metallurgy to pharmaceuticals. The properties of compacted powder beds continually evolve as constituent particles move, deform, and consolidate in response to applied stress. Accordingly, both die wall stresses and electrical transport increase as densification enhances particle contacts and stress transmission. The underlying particle-particle and particle-die physics that influence bulk properties of the compacted powder bed remain incompletely understood. Here we discuss efforts to better understand processing-structure-properties-performance relationships in die compaction by synergistically linking experimental measurements of die wall stresses and electrical conductivity with particle-based computational simulations. Experiments provide information about macroscopic behaviors of materials during compaction, while modeling provides insight into particle-particle and particle-die interactions that give rise to the observed bulk behaviors. This approach provides steps towards an ability to predict the results of die compaction based on fundamental material properties rather than empirical testing. |
