Abstract
The paper presents the results of investigations of mechanical properties of sinter obtained from a mixture of elementary iron, copper and nickel powders milled in a ball mill for a period of 60 hours. Sintering was done by hot-press- ing technique in graphite matrix. The following manufacturing parameters were used: pressure 35 MPa, temperature 900 °C, time 3 minutes. Investigations of the obtained sinterings included: density, porosity, hardness and static tensile test. Observations were also made of microstruc- ture and fracture surface of broken samples using an electronic scanning electron microscope (SEM). The study was conducted to determine the suitability of manufactured composites for the manufacture of metal-diamond tools. The influence of chemical composition, microstructure and mechanical properties of the produced sinters was investigated.
