Abstract
For the first time, the elastic constants c11, c12, and c44 of disordered cubic titanium monoxide TiOy were determined depending on the oxygen content y in the homogeneity region from TiO0.80 to TiO1.25. It has been established that the values of the elastic moduli depend on the oxygen content y and the crystallographic direction [hkl ]. Large changes in the elastic characteristics of TiOy depending on the [hkl ] direction indicate a strong anisotropy of the elasticity of disordered cubic titanium monoxide.
