From: Constitutive Law and Flow Mechanism in Diamond Deformation
Bright-field (BF) TEM micrographs of the diamond sample recovered from room-temperature deformation.
(a) Large grains almost free of dislocations are surrounded by small-grain areas; for smaller grains diffraction patterns exhibit spotty Debye rings. (b) BF TEM micrograph near [
] zone axis shows numerous {111} cleavages cutting through a large broken grain. Note that the curved cracks consist of nano-steps along {111} cleavages, as detailed in the inset.
