Characterisation of powder bulk, dynamic flow and shear properties in relation to die filling

This is the authors' abstract. We don't add key points for this paper.

Understanding powder behaviour during preparation, transfer and filling of dies is important in powder metallurgy since each step influences the quality of the final component. For high productivity and quality during manufacture, it is essential that process and powder characteristics are compatible. This investigation of the bulk, dynamic flow and shear properties of four materials demonstrates that die filling effectiveness correlates well with many powder properties. Thus the availability of accurate information about the flow and bulk properties of powders should allow reliable prediction of die filling efficiency, removing any need for the more usual 'trial and error' approach.
