Abstract : An examination of the crystal structure of nonordered alloys and the superstructures of Ti2O, Ti3O and Ti6O reveal the preservation of a strong generic connection between the structure of these compounds and structure of the matrix solid solution of oxygen in alpha-Ti from which they are formed. Presently available experimental data regarding the structure and properties of solid solutions of oxygen in titanium are insufficient for constructing the phase diagrams for the titanium-enriched region of the Ti-O system. It is too soon to discuss the significance of ordering Ti-O alloys in practice, since the actual titanium alloys consist of not more than 0.3% oxygen. During titanium oxidation and that of its alloys even if the ordering process is occurring in the suboxide 'alpha-deposited' layer no slowing of the growth of the scale is noticed.
