Abstract

The High Temperature Annular Shear Cell was used was used to characterise the flow properties of five ceramic powder samples with different particle size distributions at ambient temperature and at 500°C. A significant increase of powder cohesion was observed with increasing temperature. A model combining a continuum approach and a particle–particle interaction description was used to correlate the powder tensile strength with the interparticle forces. The dependence of the tensile strength on powder consolidation and temperature is correctly described by the model.
