Abstract

The aim of this paper is to present the effect of the pressing speed on the press ability of the iron powders. For the research iron powder type FERSINT RI 180/3.0 with different particle size was used. The cylindrical samples with 12 mm diameter have been processed by unilateral die pressing at three pressures 200, 300 and 400 MPa. The influence of the particle size, pressure and pressing speed on the compacted samples was studied. It is shown that the pressing speed plays an important role in the pressing process of iron powders..
