Supercapacitors (SCs) are one of the most promising electrical energy storage technologies
systems due to their fast storage capability, long cycle stability, high power density, and …

Over the last two decades, many studies have contributed to improving our understanding of
the brittle failure mechanisms of boron carbide and provided a road map for inhibiting the …

Dislocation slip, deformation twinning, phase transformations, and fast fracture are energy
dissipation mechanisms that accommodate mechanical loading in materials. The …

Twins have been proven to greatly enhance the hardness, toughness, thermal stability, and
wear resistance of materials. However, the formation of twins in transition nitride ceramics is …

The abnormal brittle failure of superhard boron carbide (B 4 C) and other icosahedral solids
arises from the shear-induced amorphization. Mitigating the amorphization in these …

Consolidated boron carbide (B 4 C) composites are extremely hard but have been shown to
undergo stress-induced amorphization when subjected to high velocity impact. This …

Boron carbide and boron suboxide are attractive for their low densities and ultrahigh
hardness values, yet they exhibit poor fracture resistance. Strategies to improve mechanical …

Boron carbide undergoes stress-induced amorphization when subjected to large non-
hydrostatic stresses that exceed its elastic limit. This has been proposed as the source for …

The influence of carbon nanotubes (CNTs) on the mechanical properties and structure
formation during reactive sintering of B 4 C materials with Si addition was studied. Upon …

Interaction between boron carbide and silicon was studied at 1400–1700℃ in a vacuum.
The results at 1400℃ suggest that silicon substitutes a single atom of carbon per formula …
