Abstract: Transmission electron microscopy has been used to study the structural features of boron carbide treated in a high-pressure shear chamber with diamond anvils in the pressure range 25–55 GPa. Such a treatment has been shown to lead to the predominant crack formation along planes $\{10\bar{1}1\}$ and $\{10\bar{1}2\}$ and also the formation of polytypes in the $\{10\bar{1}1\}$ planes and strain bands in the $\{10\bar{1}2\}$ planes.
