  • Boron carbide (B4C) is the third hardest material in nature, but applications are hindered by its brittle failure under impact. We found that this brittle failure of B4C arises from amorphous shear band formation due to the deconstruction of icosahedral clusters, and based on this model, we suggest and validate with quantum mechanics (QM, PBE flavor of density functional theory) that a laminated B4C–B6O composite structure will eliminate this brittle failure. Using QM to apply shear deformations What is Boron carbide?To improve the flexibility of B4C, we use our model for the origin of brittleness to propose a laminated composite structure of B4C–B6O. We use QM to examine the shear deformation along various possible slip systems to understand the deformation mechanism for a composite structure. We find that the (001)/[100] slip system requires the smallest maximum shear stress (38.33 GPa), essentially the same as the ideal shear strength (38.97 GPa) of perfect B4C, indicating a similar What is Boron carbide?Boron carbide (B4C) is the third hardest material in nature, but applications are hindered by its brittle failure under impact.

Especially in light armor, reactor neutron absorptions, etc. As boron carbide can be manufactured more easi Boron carbide (B4C), is among the hardest materials used in manufacturing. Its hard surface and strong chemical bonds minimize wear even in harsh environments. This is why it's been used to make bulletproof vests, tank armor, and other extreme applications. Its hardness offers excellent protection and its light weight maximizes fluidity. This material also has a high neutron absorbance capacity, making it a good choice for radiation shielding. Therefore, it is widely used in the nuclear and othe The boron-carbide crystal is a rhombohedral crystal, and its crystal lattice is the D3d5R3m space lattice. The rhombohedral lattice can be described as an icosahedron-shaped primitive cell grid that extends diagonally in the space. The c-axis is the same as the diagonal of the area. A linear chain is formed by connecting three boron-atoms to an adjacent icosahedron. Three of the 12 icosahedral position are found on the chain. If the B-atom is due to the position of the icosahedron, and the C-ato

The pressure induced transformation of the rare β Fe2O3 phase

The pressure-induced transformation of the rare β-Fe2O3 phase has been studied for the first time, leading to the identification of a new iron(III) oxide polymorph, ζ-Fe2O3. The transformation of β-Fe2O3 into ζ-Fe2O3 occurs above 30 GPa, and the new phase withstands pressures of up to ~70 GPa, which is well above the thresholds for the pressure-induced transformations of α-Fe2O3 or γ-Fe2O3. More strikingly, ζ-Fe2O3 remains stable after pressure release and at room temperature. This remarkable ob
