The alloying of vanadium with substitutional elements of group IVa (Ti, Zr, Hf) significantly increases its high-temperature strength. However, in long service in gaseous media containing oxygen as an impurity, its mechanical properties become poorer as the result of the increase in oxidation rate, the interaction of oxygen with the alloying element, escape of it from the composition of the solid solution, segregation of the oxygen and the reaction products at the grain boundaries, etc. It is possible to eliminate these if in advance a structure with thermodynamically stable oxide particles of the necessary morphology and dispersion is formed by internal oxidation. The purpose of this work was a study of the influence of internal oxidation on the structure and stressrupture strength of vanadium alloyed with titanium.
