For this purpose, the boron carbide addition quantity was changed as 2, 5 and 10 wt%. In all of the experiments, hot pressing process was carried out at 35 MPa, at 700°C and sintering time of 3 min. Microstructure and phase composition of segments were determined by Scanning Electron Microscopy, Energy Dispersive Spectroscopy (SEM/EDS) and X-ray diffraction (XRD) analysis. Hardness and bending strength values were measured by hardness and three-point bending test devices, respectively. Hardness and bending strength values of segments changed depending on boron carbide rate.trSegments, boron carbide, hot pressing.Article
