The ordered distribution of carbon atoms in titanium carbide

Abstract The combined techniques of selected-area electron diffraction and dark-field electron microscopy have been used to determine the ordered distribution of carbon atoms formed after low-temperature annealing in crystals with composition near Ti2C. The superstructure is based on a cubic lattice similar to that previously determined by neutron diffraction and is consistent with the antiphase boundary contrast observed in dark-field images.
