The creation of high-strength heat-resistant alloys based on titanium is of great scientific interest. Doublephase titanium (at + 13) alloys are widely used at present. The alloying sets for these alloys are mainly developed with the purpose of increasing their strength and heat resistance by solution strengthening of the phases with substitutional elements. However, the increasing strictness of the requirements on the level of their mechanical properties makes it necessary to create titanium alloys that can be strengthened by the segregation of an intermetallic phase or chemical compounds. An important problem in the development of such alloys is the choice of the optimum composition and the attainment of the requisite dispersity and uniformity of distribution of segregations of strengthening phases in the structure. In this connection, carbon and boron, poorly soluble in titanium and forming independent carbide and boride segregations, are of some interest as alloying additives to these alloys.
