Boron Carbide is a ceramic material of technological application due to its extreme hardness and high chemical and thermal stability. The effect of synthesized boron carbide addition on pressureless sintering and hot-pressing of a commercial B4C was investigated. B4C synthesized by carbothermal reduction using carbon black as carbon source was mixtured in 10, 30 and 50 wt% to a commercial B4C. Powder mixtures were compacted into pellets and sintered by pressureless sintering at 2050 °C/30min Samples were compared to a pure commercial B4C and characterization results have not showed great differences. Relative densities of as-sintered materials exceed 93% of theoretical for all compositions and microhardness Hv of ∼ 32 GPa was obtained.

This paper presents the mechanical and machinability properties of aluminium 6061 alloy reinforced with boron carbide composite is compared with the addition of graphite particles with AlB4C. The composites were fabricated by stir casting process. The experimental results showed that the hardness of the composite increases with the increasing addition of boron carbide. Tests for machinability characteristics was carried out with carbide tool at different cutting speeds keeping feed and depth of cut as constant. The machining tests revealed that the addition of graphite to Al-B4C composite has enhanced its machining properties.

Boron Carbide B4c

The hardness, toughness and sum of cracks measurement of fine-grained WC - Co hard metals were studied. Thirty commercial and experimental hard metal grades with different additives such as boron carbide ( B 4 C ), vanadium carbide ( VC ), chromium carbide ( Cr 3 C 2) and silicon carbide ( SiC ) were prepared in a commercial sinter HIP furnace. Physical, mechanical and microstructure properties were investigated to build up a representative hardness/sum of cracks measurement band. This band was then used to estimate the most effective sintering temperature and the amount of each additives. Afterwards, influence of grain growth inhibitors in optimum condition were compared. The results showed that the grades, doped with B 4 C and VC as growth inhibitor exhibits more hardness than other comparable doped alloys. However, Cr 3 C 2 is favorable in toughness improvement.
