Abstract
The compaction behavior of steel powders, hard metals. and ceramic powders have been investigated using a newly developed high pressure triaxial resti ng facility. Results from isostatic compaction, simulated closed die compac tion, and compaction along different radial loading paths in stress space a re presented for six commercial powders. The experimental data are compared and considerations regarding the constitutive modeling of the compaction r esponse of the different classes of materials are presented.
