This study was carried out to produce and characterize B4C - TiB2 ceramics by spark plasma sintering. Initial B4C and TiB2 powders were mixed in ethanol solution with YSZ balls for 1 hour. Sintering was performed with 5, 10, 15 and 20 volume % TiB2 containing mixtures respectively in disc-shaped graphite dies. The applied pressure was 40 MPa at 1760 °C for 5 minute sintering duration. The improvement of low sinterability and low strength of B4C was investigated as well as strength of flexibility, hardness and fracture toughness. The obtained products were characterized by X-ray diffraction and SEM imaging. The hardness values were measured under 1000 g load and the density values were measured with Archimedes' principle. The 3-point bending tests and modulus of elasticity measurements were also conducted.

ABSTRACTIn this work results are presented regarding carbon composites produced by high energy mechanical milling and consolidated by spark plasma sintering. The involved energy input in such a processing method has been used to develop composite materials and to synthesize effective in-situ reinforcement. In the as milled and sintered composites various dispersions of graphene, graphitic carbon, and diamonds in an amorphous matrix are found. The graphene, graphitic carbon and diamond phases are synthesized primarily during milling. The TEAM-05 microscope has been used for characterization that is complemented with Raman results. The spark plasma sintering method enhances the presence of graphene, graphitic carbon and diamonds.

The influence of different sintering temperatures during Spark Plasma Sintering (SPS) process on microstructure of La-Ca-Sr-Mn-O ceramics has been studied. The powders of La0.67Ca0.33-xSrxMnO3 (x = 0.33; 0.03) (LCSM) perovskite were prepared by milling of the stoichiometric amounts of the starting materials - lanthanum oxide (La2O3), calcium oxide (CaO), strontium carbonate (SrCO3) and manganese oxide (MnO2), and subsequently calcinated twice. After the second calcinations the LCSM powders were treated by SPS method at four different temperatures (1000°C, 1150°C, 1200°C and 1250°C), at uniaxial pressure of 50 MPa in a vacuum. The microstructure characterizations were done by polarized light microscopy and scanning electron microscopy. The microstructural observations showed that increasing sintering temperature leads to an increase of grain size. The energy dispersive spectral (EDS) analysis confirmed that higher sintering temperatures cause changes in the phase composition of the investigated LCSM perovskite materials. The benefits of the LCSM samples preparation by SPS process are discussed.
