The effect of milling on the particle size and mechanical properties Tungsten Carbide - Cobalt composite were investigated. First, raw materials ratios by mechanical milling for 4 hours at 300 rpm were mixed. The powder in the optimum temperature 1350°C at a rate of temperature rise 50°C / min and shelf life of 4 minutes and the pressure MPa 30 were sintered in SPS. The results indicated nearly...

ZrB2-TiC composites with and without nano-sized carbon black as the sintering additive were densified through spark plasma at 1900 °C for 7 minutes under applied pressure of 40 MPa. The role in densification behavior, phase arrangement, microstructural characteristics mechanical properties sintered then investigated. While both composite samples found to be fully sintered, thermodynamic reactiv...

A high-pressure silicon infiltration technique was applied to sinter diamond–SiC composites with different diamond crystal sizes. Composite samples were sintered at pressure 8 GPa and temperature 2170 K. The structure of composites was studied by evaluating x-ray diffraction peak profiles using Fourier coefficients of ab initio theoretical size and strain profiles. The composite samples have pr...

Additive manufactured porous SiC is a promising material applied in extreme conditions characterised by high temperatures, chemical corrosion, and irradiation etc. However, residual Si’s existence deteriorates its performance limits application harsh environments. In this study, B4C was introduced into the selective laser sintering process of SiC, effects on forming ability, pore parameters, mi...
