Ultrahard sutures in nanocomposite C2-BN.
(a–c) HRTEM images at the junction between diamond and cBN domains. The FFT inset shows the rotation angles between adjacent diamond or cBN domains. (d) HRTEM and corresponding SAED pattern from a typical junction indicates that only nano-twinned diamond and cBN are present at the interface. Dislocations and stacking faults at the interface are found in the region marked by the white rectangle in (b) and (d).
