From: Constitutive Law and Flow Mechanism in Diamond Deformation
TEM micrograph of the diamond sample recovered from the deformation experiment at 1200 °C.
(a) Weak-beam dark-field (WBDF) micrograph of a typical grain exhibiting numerous entangled dislocations and planar features (diffraction vector is indicated by g).(b) A DF micrograph showing planar deformation features. The observed moiré fringes are classically characteristic of stacking faults and microtwins; (c) BF micrographs of a grain exhibiting numerous {111} microtwins. The inset shows the diffraction pattern of an area selected in the lower left corner of the image; splitting reflections and streaks are due to thin alternated twinned domains.
