urn:hdl:2117/13969 Experimental study of mass flow and apparent density in powder metallurgy die filling Riera Colom, María Dolores Istúriz, Álvaro Prado Pozuelo, José Manuel Àrees temàtiques de la UPC::Enginyeria dels materials::Metal·lúrgia Powder metallurgy -- Mathematical models Granular materials Metal·lúrgia -- Models matemàtics Materials granulars Die filling is the first step in the process of powder compaction. The density distribution after die filling on the powder properties and the method of filling. In this work the authors study the effects of powders characteristics, size and morphology, and shoe speed on the type of mass flow during the filling and the resulting density distribution. Experimental results for different powders and die geometries are presented. Three flow regimes have been identified and their influence on apparent density is discussed Postprint (published version) 2005 Conference report http://cataleg.upc.edu/record=b1273214~S1*cat Open Access European Powder Metallurgy
