## Description

- description: "Grain boundaries, twins, and defects are considered to influence the
    thermomechanical behavior of any covalent ceramic. As a result, monolithic B4C
    samples show different shapes, and the present theoretical models fail to fit
    them over the entire temperature range. We fabricated a novel high-density boron
    carbide to overcome these issues and evaluated its high-temperature bending strength.
    The as-obtained ceramic comprises boron carbide grains and a fine grain-boundary
    metal Pt framework. The material shows a decreased strength, which is due to a
    non-linear increase in the volume expansion coefficient of the B4C.\r\nRecovery
    in strength above 1000 ℃ is due to the presence of twins, their growth, and rearrangements.
    We consider twin rearrangements evidence for a novel ‘micro’ mechanism of high-temperature
    stress accommodation for the boron carbide bulks."
