The data on the influence of thermomechanical treatment modes on characteristics of the short-term strength and plasticity of vanadium alloys of different systems (V–Ti–Cr, V–Zr–C, V–Cr–Zr, V–Cr–W–Zr, V–Cr–Ta–Zr) are generalized. It is shown that an application of a modified mode ensures an appreciable increase in the short-term strength at room temperature and elevated temperatures, while maintaining an acceptable plasticity. The principal mechanisms of metastable carbide transformations into oxicarbonitride phase particles with phase-forming elements participation and the conditions of their realization are discussed.
