摘要:Abstract(#br)Electrical conductivity is an essential property for machining of sintered boron carbide especially by wire electrical discharge machining (WEDM) process. Pure boron carbide was spark plasma sintered to full density at 2050 °C. Rietveld refinement on XRD analysis...

摘要:Abstract(#br)Boron carbide experiences glass-like brittle behavior when subjected to high shear stresses due to stress-induced amorphization. Strategies to mitigate amorphization have primarily focused on Si/B co-doping. However, the overall mechanical properties of Si/B co-d...

摘要:Abstract(#br)In the presented work, high purity boron carbide (purity of 99.9%, and bulk density 1.8 g/cm 3 at 20 °C) compounds were gamma-irradiated at dose rate of D = 30 rd/sec using Co 60 gamma source. The irradiation of the samples at different gamma doses (5·10 9 ; 1·10...

摘要:... To overcome these issues, we fabricated a novel high-density boron carbide and evaluated its high-temperature bending strength. The as-obtained ceramic is composed of boron carbide grains and a fine grain-boundary metal Pt framework. The material shows a decreased strength, ...

摘要:Abstract(#br)Reduced graphene oxide (rGO) sheets were uniformly dispersed in boron carbide ceramics by a heterogeneous co-precipitation method. This approach was used to improve the fracture toughness of boron carbide ceramics and to address the problem of agglomeration of gra...

摘要:Abstract(#br)Fully dense boron carbide discs were achieved by spark plasma sintering boron carbide powders with 10 wt% silicon. The silicon did not diffuse into boron carbide grains to produce a solid solution of Si-doped boron carbide; instead the silicon reacted with impur...

摘要:Abstract(#br)Boron carbide is extremely hard but has been shown to undergo stress-induced amorphization when subjected to large nonhydrostatic stresses. This localized amorphization has been associated with the sudden loss of its shear strength and poor ballistic performance. Rec...

摘要:Abstract(#br)A self-assembly polymerization process was used to prepare graphene oxide/boron carbide (GO/B 4 C) composite powders, spark plasma sintering (SPS) was used to fabricate reduced graphene oxide/boron carbide (rGO/B 4 C) composites at 1800 °C and 30 MPa with a soaking...

摘要:Abstract(#br)Boron carbide has a wide range of solubility, but the effects of stoichiometry on its microstructure and mechanical response are not well understood. In this study, detailed microstructural characterization was carried out on three hot-pressed B-rich boron carbide sa...

摘要:Abstract(#br)Boron carbide with purity levels higher than that achievable by traditional manufacturing processes using an electric arc furnace (EAF) was produced by a novel low cost, low energy, environmentally friendly process of carbothermic reduction of boric acid (H 3 BO ...
