The microstructures of samples which had been fabricated by hot pressing TiN and TiC powders were studied by means of transmission electron microscopy. The carbonitride had a face-centered cubic structure, but there was no evidence of ordering of the interstitial atoms, and (111)-type twinning with a twin plane of Ti atoms was observed. Incoherent twin boundaries or steps were found to connect coherent twin boundaries which lay on (111). It was found that (a/6)<11¯2>-type dislocations were found to be associated with atomic steps at the twin boundary.
