- Abstract
The peculiarities of compaction and sintering of samples obtained from iron powder mixtures with different types of pore-formers (ammonium bicarbonate, sodium hydrocarbonate, sodium chloride) is contemplated. Compaction was performed unilaterally in a closed cylindrical matrix and sintering was carried out in reducing environment in a container with filling. Compression and ejection curves for the samples obtained from specified mixtures in the range of pressure 200-800 MPa were plotted. The influence of pore formers, used in the experiment, on the compaction mixtures of the system "iron - pore-former" is established. The dependencies of the changes in linear dimensions of sintered samples for specified values of compaction pressure within indicated range are built.
