The cold isostatic pressing of composite powders. 1: Experimental investigations using model powders
- Cambridge Univ. (United Kingdom). Engineering Dept.
The cold isostatic pressing of composite powders was experimentally investigated using model rigid-plastic composite powders consisting of mixtures of Plasticene spheres and various amounts, sizes and shapes of rigid inclusions. The model powders were densified in a pressure vessel which was instrumented to allow for the continuous monitoring of the pressure and relative density of the powders. Several inclusion properties significantly affect the densification of the composite powders: the inclusion volume fraction, the size of a rigid inclusion relative to the plastic spheres and the aspect ratio (maximum dimension/minimum dimension) of an inclusion. Powders with a high volume fraction of inclusions, small relative inclusion size, and/or large inclusion aspect ratio required the greatest pressures to densify.
