Abstract
We have examined the influence of nonstoichiometry and order-disorder phase transformations on the basis period (of type B1) of the structure of titanium carbide TiCy (0.5<y<1.0). We found that ordering of titanium carbide TiCy with formation of superstructures of the type Ti Ti2C and Ti3C2 leads to growth of the period of the basis crystal lattice in comparison with the disordered carbide. Taking the change in the lattice period into account, we discuss the question of the directions of the static displacements of atoms near a vacancy.
