The effects of stoichiometry on the atomic structure and the related mechanical properties of boron carbide (B(4)C) have been studied using density functional theory and quantum molecular dynamics simulations. Computational cells of boron carbide containing up to 960 atoms and spanning compositions rang...
Mechanical propertyWe fabricated boron carbide-silicon carbide (B4C–SiC) composites by hot-press sintering without additives and evaluated the crystal phase, relative density, microstructure, and mechanical properties of the sintered body. When B4C and SiC were uniformly dispersed in the composite, ...
mechanical properties of the CCBs were investigated by using scanning electron microscopy (SEM), a shore hardness test, and a flexural strength evaluation. The results revealed that the oxygen content increased with stabilization temperature and the physical properties of the CCBs were considerably ...

To improve the mechanical properties and tribological characteristics of boron carbide (SiC) ceramic, silicon carbide as incorporation phase was added into boron carbide (B4C) matrix. The results showed that the incorporation of SiC phase led to denser microstructure and lower porosity. When the cont...
Then, mechanical properties of multi-layered materials, obtained by stacking dense and porous layers that should contain enough porosity to initiate crack deflection, according to the models, were evaluated. 展开 关键词: Boron carbide Silicon carbide Laminar materials Tape casting Rupture Crack ...
