Silicon carbide (SiC) fiber-reinforced ceramic matrix (SiC f/SiC m) composites have been
identified as potential materials for nuclear fuel cladding. These composites are fabricated …

In the last few decades, a variety of brittle materials (ceramics and glasses) have found new
applications in the armor, nuclear and semiconductor, and energy storage industries …

Raman spectroscopy has been used extensively to characterize the influence of mechanical
deformation on microstructure changes in biomaterials. While traditional piezo-spectroscopy …

Boron carbide is extremely hard but has been shown to undergo stress-induced
amorphization when subjected to large nonhydrostatic stresses. This localized …

The present work reports a detailed mechanistic interpretation of the role of the solubility of
dopants and resultant midgap defect energies in band gap engineering. While there is a …

Icosahedral boron-rich solids fall second in hardness to diamondlike structures and have
been the subject of intense investigations over the past two decades, as they possess low …

Macroscale experiments for structural response of materials often do not capture
deformation features at the atomistic scale. This limitation becomes more pronounced in …

Shock compression subjects materials to a unique regime of high quasi-hydrostatic pressure
and coupled shear stresses for durations on the order of 1–10 nanoseconds for laser-driven …

Spark plasma sintered boron carbide (B 4 C) has been tested for damage evolution
characteristics. Three distinct failure regions were identified during the scratch process of B …

Boron carbide suffers from a loss of strength and toughness when subjected to high shear
stresses due to amorphization. Here, we report that a small amount of Si doping (~ 1 …
