Abstract
The effect of nonstoichiometry on the lattice constant of cubic vanadium carbide VCy (0.65 < y < 0.875) is studied. It is found that the ordering of vanadium carbide VCy with the formation of superstructures V6C5 and V8C7 leads to an increase in the base lattice constant in comparison with disordered carbide. Taking into account the change in the lattice constant, the direction of the static displacements of atoms near the vacancy is discussed.
