Beschreibungen/Notizen

• The ordered structures and phase transitions in TiC 0.62 and TiC 0.59 are investigated on the high resolution neutron diffractometer. It is established, that low-temperature trigonal δ″(sp.gr. R 3 ̄ m or sp.gr. P3 121) and high-temperature cubic δ′(sp.gr. Fd3m) ordered structures, according to the temperature, exist in the investigated carbide samples. Under heating, the sample TiC 0.62 experiences the order-order (δ″( R 3 ̄ m )→δ′(Fd3m)) phase transition at 770°C and then, the order-disorder ((δ′(Fd3m)→δ(Fm3m)) phase transition at 790°C.
