Single crystals of TiC1−x. and NbC1−x. were studied by elastic neutron diffuse scattering at room temperature in the (110) reciprocal lattice plane; the spectra of TiC0.76, TiC0.79and NbC0.73 were analysed by the Sparks and Borie method, which allowed to determine the first Cowley-Warren. short-range order coefficients and a shortening (0.03 Å) of the average first neighbor metal-carbon distances. The order-disorder transformation in TiC1–x (0.52 ⩽ 1–x ⩽ 0.67) was studied by high temperature powder neutron diffraction; the transition temperatures (≃760– 790°C) and critical coefficients β were determined. The results are discussed in terms of interatomic pair potentials.
