Annotatsiya

Phase transformations in titanium oxycarbide TiC0.545O0.08 have been studied by the methods of neutron diffraction and X-ray structure analysis. It was established that the ordered cubic structure δ′ (sp. gr. Fd3m) of the oxycarbide sample is the low-temperature ordered phase existing up to 990 K. The order-disorder phase transition (990 K) results in the formation of an ordered trigonal structure (sp. gr. or R3m or P3121). The α-Ti-phase is separated at the temperature 1020 K. The order-disorder phase transition was found at T = 1040 K.
