Powder metallurgical processes such as isostatic pressing, sintering, powder compaction and additive manufacturing are being extensively used to manufacture metallic and ceramic parts. Often the quality of the products obtained through these processes is greatly affected by the presence of particle shape and size inhomogeneities.
In this project, EDEM was used to study the phenomenon of segregation during the filling of a cylindrical die with a metallic binary mixture. Both stationary and vibrating dies were considered to investigate the effects of vibration amplitude and vibration frequency on segregation and also the compaction of the particles.
