Anisotropy of elastic properties of disordered cubic titanium monoxide TiOy

For the first time, the elastic constants c₁₁, c₁₂, and c₄₄ of disordered cubic titanium monoxide TiO_y were determined depending on the oxygen content y in the homogeneity region from TiO_0.80 to TiO_1.25. 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 TiO_y depending on the [hkl ] direction indicate a strong anisotropy of the elasticity of disordered cubic titanium monoxide.
