Microstructure of nanocomposite C2-BN.
(a) TEM lamellae obtained from a C2-BN bulk sample before focused ion-beam (FIB) thinning. (b,c) TEM images of the area with the red box in (a). The inset of (b) shows a selected area diffraction (SAED) pattern (d and e) HRTEM images of the nanotwinned diamond and cBN domains. Insets show calculated FFT patterns of the two main domains.
