Résumé

The influence of copper content on the enhancement of the bending strength of the iron based highly porous sintered powder materials was studied. The porous samples were manufactured by replica technique using the ammonium bicarbonate powder as a space holder. The amount of the ammonium bicarbonate in a starting powder mixture was 50% volumetric. The amount of the copper additive was 0.10% and 20% by weight, respectively. The influence of the copper additive on the
compaction behavior of the powder mixtures has been discussed. The microstructure of the sintered highly porous samples is presented.
