## Description

- description: 'High density (99.5%) ceramic composite composed of titanium boride
    and boron carbide (70/30 vol%) was obtained by spark plasma sintering and was
    tested by 3-point bending test in Ar atmosphere at 1800 °C. Bending strength was
    high, around 1.1 GPa. The strength–strain curve presents a peculiar shape composed
    of three regions where elastic and plastic deformations are active with a different
    weight. Based on transmission electron microscopy observations we propose a process
    of mechanical energy absorption driven by shear stress in the boron carbide crystals:
    stacking faults with (1-11) and (011) stacking planes and twins with (1-11) twinning
    plane rearrange into nano-twins with (10-1) twinning planes, orthogonal but equivalent
    to the initial ones. This rearrangement mechanism provides in the first instance
    a plastic signature, but further contributes strengthening.'
