In this study, the density of powder metallurgy compacts was measured by means of small indentation. Zinc (Zn) and aluminum (Al) tablets were fabricated by cold compaction of powders: different tablet densities were obtained by changing the packing pressure. Instrumented indentation tests were carried out by means of flat cylindrical indenters having diameters of 1mm and 2mm. After a calibration procedure, the slope of the indentation curve or the indentation load can be used for the density evaluation.
