A comparative investigation of the influence of thermomechanical treatment modes on the structural-phase state and mechanical properties of a V–Cr–Zr–Ta low-activation vanadium alloy is performed. It is demonstrated that the use of thermomechanical treatment improves the level of short-term strength at room and elevated temperatures. The alloy is characterized by high ductility in a wide range of temperatures irrespective of the regimes of thermomechanical treatment. It is found out that the V–Cr–Zr–Ta alloy possesses higher thermal microstructure stability and mechanical properties compared to those of the V–Ti–Cr alloys.
