摘要：

The concentration boundary of the formation of the omega-phase in binary titanium alloys with d-metals of 4-11 groups of 4-6 periods were studied by X-ray diffraction analysis. It is established that the omega-phase is formed in all the alloys studied, with the exception of Ti-Zr alloys. It is shown that the minimum concentration limit of the formation of the omega-phase is determined by the position of the curve of the finish of the martensitic beta -> alpha '(alpha '') transformation (M-f). For most of the studied titanium alloys, concentrations were determined at which the M-s and M-f points correspond to a temperature of 20 degrees C. The conditions for the formation of the omega-phase in titanium alloys were compared with the conditions for its formation in zirconium alloys.
