The Fe-Cu-Ni powders premixed and ball-milled for 30 hours, were used for the experiments. The influence of manufacturing process parameters on microstructure and mechanical properties of produced sinters was investigated. Sintering was done by hot-pressing technique in graphite mould. The powders were consolidated to a virtually pore-free condition during 3 minutes hold at 35MPa and 900°C. Investigations of the sintered materials included: density, hardness, static tensile test and X-ray diffraction (XRD) analysis. Microstructural and fractographic observations were also made with a scanning electron microscope (SEM). The obtained results indicate that the sintered parts have a high density, close to the theoretical value, good plasticity, relatively high hardness and yield strength, and are characterized by a coarse-grained microstructure.}, type={Article}, title={Processing and Characterization of Fe-Cu-Ni Sinters Prepared by Ball Milling and Hot Pressing}, URL={http://www.czasopisma.pan.pl/Content/116398/PDF/AMM-2020-3-31-Borowiecka.pdf}, doi={10.24425/amm.2020.133233}, keywords={matrix, diamond, hot pressing, diamond tools}, }
