| Abstract: | The structure of Ti-Nb-B alloys that are cast and annealed at subsolidus temperatures and at 1400°C is experimentally analyzed
(x-ray diffraction, metallography, and electron probe microanalysis), and so are temperatures of their phase transformations
(differential thermal analysis and pyrometry). No ternary phases are found in the alloys. Projections of solidus and liquidus
surfaces, an isothermal section at 1400°C, and a vertical section at 7.5 at.% B are constructed. A reaction scheme is proposed
for alloy crystallization.
