| Abstract Scope |
Fields ranging from powder metallurgy to pharmaceuticals utilize die compaction to consolidate powders. The properties of compacted powder beds continually evolve as constituent particles move, deform, and consolidate in response to applied stress. Accordingly, electrical transport increases as densification enhances particle contacts and stress transmission. Here we discuss efforts to better understand processing-structure-properties-performance relationships in die compaction by synergistically linking experimental measurements of powder properties 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. Of particular note are efforts to extend particle-based simulations from idealized spherical particles to more realistic shapes. This approach provides steps towards an ability to predict the results of die compaction based on fundamental material properties rather than empirical testing. |
