    Abstract

    An experimental device has been developed intended for the material characterization of powder metals. The experimental approach rests on the uniaxial (die) compaction of powders. The output is the compaction force–depth relationship together with the die wall/powder contact pressure determined at eight different points using pressure sensors placed on the die wall. The recorded data are of such high quality that it can be expected that inverse methods aiming at material characterization can be applied without numerical instability problems. Finite-element methods are used in order to verify the outcome of the experimental approach for the particular case of WC/Co powder materials mechanically described by using an advanced elasto-plastic material model with a large number of constitutive properties.
